Trump warns of fresh Iran strike as Tehran threatens Gulf internet cables

The brief

The central warning is about a possible new US operation against Iran and a possible Iranian response against communications infrastructure. Trump referred to another operation as “Epic Fury,” raising fears that the conflict could enter a renewed phase. Iran’s warning shows that any escalation could extend beyond battlefields. Two Iranian security officials told Reuters that Tehran had prepared plans to target undersea communications cables in the Gulf. One official said Iran could try to block repairs after cable cuts, prolonging disruption to internet connections and other communications. Yadollah Javani said seven major cables beneath the Strait of Hormuz could be targeted. The threats remain tied to a possible future attack, not a reported cable strike in the article. Renewed fighting could therefore affect regional stability, digital connectivity, oil prices and wider economic activity. Foreign ministers from Turkey, France and other countries urged diplomacy, warning that another offensive could spread the war.

01

What did Trump warn the United States might do, and what did Iran threaten to target if a new attack occurred?

The central warning is about a possible new US operation against Iran and a possible Iranian response against communications infrastructure. Trump referred to another operation as “Epic Fury,” raising fears that the conflict could enter a renewed phase. Iran’s warning shows that any escalation could extend beyond battlefields.

Two Iranian security officials told Reuters that Tehran had prepared plans to target undersea communications cables in the Gulf. One official said Iran could try to block repairs after cable cuts, prolonging disruption to internet connections and other communications. Yadollah Javani said seven major cables beneath the Strait of Hormuz could be targeted.

The threats remain tied to a possible future attack, not a reported cable strike in the article. Renewed fighting could therefore affect regional stability, digital connectivity, oil prices and wider economic activity. Foreign ministers from Turkey, France and other countries urged diplomacy, warning that another offensive could spread the war.

02

What are undersea communications cables, and what kinds of information do they carry?

Undersea communications cables are physical cables placed on the seabed to connect distant countries, network systems and communications hubs. They matter because the internet is not purely wireless or floating in the cloud. Much of the information people exchange crosses these physical links, so damage can affect connectivity across borders.

The article refers specifically to Gulf cables carrying internet connections and other communications. That includes digital traffic moving between networks, such as messages, business data and online services. The source does not list every type of information carried; these examples reflect the normal function of communications networks rather than a detailed list in the article.

Their importance becomes clear in the Iranian threat. Two security officials said Tehran could cut cables and try to prevent repairs, prolonging disruption. The result could be slower or interrupted connections in affected areas. The article therefore presents cables as strategic infrastructure, alongside military bases, energy facilities and other targets.

03

How many major internet cables did an Iranian Revolutionary Guards official say could be targeted beneath the Strait of Hormuz?

The number given in the article is seven. Yadollah Javani, deputy head of political affairs for Iran’s Revolutionary Guards, said Iran could target seven major internet cables beneath the Strait of Hormuz. The statement came as concern grew about renewed US-Israeli military action.

These cables matter because they support internet connections and other communications across the Gulf region. The article does not explain whether all seven routes serve the same destinations or carry equal amounts of traffic. It does establish that they are major cables and that Iran claimed it had access to them.

The seven-cable figure describes a potential target set, not confirmed damage. Two Iranian security officials said Tehran had prepared detailed plans and might seek to prevent repairs after cuts. That could make disruptions last longer. The threat adds communications infrastructure to the wider risks already involving military sites, energy facilities and regional stability.

04

What could happen to internet access, business operations, and regional communications if Gulf cables were cut and repairs were blocked?

Cutting Gulf cables could interrupt or weaken internet access and other communications for networks that depend on them. The article specifically warns that disruptions could be prolonged if Iran prevented repair work. That would turn a short technical failure into a continuing regional problem.

For businesses, interrupted connectivity could hinder online services, payments, data transfers, customer contact and coordination with offices or suppliers. These specific business effects are general consequences of communications outages; the article itself mentions internet connections and other communications rather than naming business systems. Regional authorities and organisations could also find routine coordination more difficult.

The scale would depend on which cables were cut and what backup routes existed. The article gives no technical estimate of outage size or duration. It does say Iran might target seven major cables beneath the Strait of Hormuz. A prolonged disruption would add economic and regional pressure to an already dangerous conflict.

05

Why are the Gulf and the Strait of Hormuz important not only for internet cables but also for global oil supplies?

The Gulf and Strait of Hormuz matter because they combine energy and communications importance in one region. Trump said oil was continuing to move through the Strait, which he called a vital shipping route for global energy supplies. Cables beneath the same waterway support internet connections and other communications.

The article links renewed military action with possible pressure on both systems. Iran’s Revolutionary Guards official said seven major internet cables beneath the Strait could be targeted. At the same time, foreign ministers warned that escalation could create serious consequences for hydrocarbon prices. A threat to shipping or infrastructure could therefore unsettle energy markets and digital networks together.

The Strait’s importance makes it a focus of international concern. Trump said oil was still moving and that the United States was getting what it wanted. France warned that further escalation would likely push up oil prices. Any new conflict could spread economic effects well beyond the Gulf.

06

How could threatening cables, data centres, and other infrastructure serve as a deterrent against a new US-Israeli attack?

A deterrent is a threat intended to make an opponent reconsider an action. In this case, Iran could signal that a new US-Israeli attack would produce consequences beyond direct fighting. Threatening cables, data centres or other infrastructure could raise the expected economic, communications and political costs of escalation.

The article gives one clear mechanism: Iranian officials said Tehran could cut Gulf undersea cables and prevent repairs. That could prolong internet and communications disruptions. Similar threats to infrastructure would aim to create pressure by putting essential systems at risk. The article does not specifically mention data centres, so their role here is a general example rather than a reported Iranian plan.

This strategy would not guarantee that an attack was prevented. It could instead widen the conflict and damage regional stability, which is why Turkey, France and other countries warned against renewed escalation. The threat is conditional on another US-Israeli campaign, and the article reports no confirmed infrastructure attack.

07

Why does the internet depend on vulnerable physical infrastructure, and how do cable routes and backup connections limit the effects of a single cable being damaged?

The internet depends on physical infrastructure because digital information must travel through equipment and network links. Undersea cables are one such link. If a cable is cut, the networks using it may lose capacity or connectivity. This is why the article treats Gulf cables as strategic infrastructure rather than invisible technology.

Cable routes and backup connections can limit the effect of one damaged line by allowing traffic to use another path. The disruption may then be smaller or shorter, depending on available capacity and repairs. However, damage to several major cables, or blocking repairs, could reduce those alternatives. The article says Iran might target seven cables and prevent repairs.

The source does not provide a map of routes, explain backup arrangements or estimate resilience. The broader point remains clear: physical geography shapes online connectivity. In the Gulf, a conflict affecting cables could create communications problems alongside threats to energy supplies and military stability.
