DUBAI – Undersea cable cuts in the Red Sea disrupted internet access in parts of Asia and the Middle East, experts said Sunday, though it wasn't immediately clear what caused the incident.
There has been concern about the cables being targeted in a Red Sea campaign by Yemen's Houthi rebels, which the rebels describe as an effort to pressure Israel to end its war on Hamas in the Gaza Strip. But the Houthis have denied attacking the lines in the past.

Undersea cables are one of the backbones of the internet, along with satellite connections and land-based cables. Typically, internet service providers have multiple access points and reroute traffic if one fails, though it can slow down access for users.
Multiple cables cut off Saudi Arabia
Microsoft announced via a status website that the Mideast “may experience increased latency due to undersea fiber cuts in the Red Sea.” The Redmond, Washington-based firm did not immediately elaborate, though it said that internet traffic not moving through the Middle East “is not impacted.”
NetBlocks, which monitors internet access, said “a series of subsea cable outages in the Red Sea has degraded internet connectivity in multiple countries,” which it said included India and Pakistan. It blamed “failures affecting the SMW4 and IMEWE cable systems near Jeddah, Saudi Arabia.”
The South East Asia–Middle East–Western Europe 4 cable is run by Tata Communications, part of the Indian conglomerate. The India-Middle East-Western Europe cable is run by another consortium overseen by Alcatel Submarine Networks. Neither firm responded to requests for comment.
Pakistan Telecommunications Co. Ltd., a telecommunication giant in that country, noted that the cuts had taken place in a statement on Saturday.
Saudi Arabia did not acknowledge the disruption and authorities there did not respond to a request for comment.
In Kuwait, authorities also said the FALCON GCX cable running through the Red Sea had been cut, causing disruptions in the small, oil-rich nation. GCX did not respond to a request for comment.
In the United Arab Emirates, home to Dubai and Abu Dhabi, internet users on the country's state-owned Du and Etisalat networks complained of slower internet speeds. The government did not acknowledge the disruption.
Undersea lines can be cut in accidents and attacks
Subsea cables can be cut by anchors dropped from ships, but can also be targeted in attacks. It can take weeks for repairs to be made as a ship and crew must locate themselves over the damaged cable.
The cuts to the lines come as Yemen's Houthi rebels remain locked in a series of attacks targeting Israel over the Israel-Hamas war in the Gaza Strip. Israel has responded with airstrikes, including one that killed top leaders within the rebel movement.
In early 2024, Yemen’s internationally recognized government in exile alleged that the Houthis planned to attack undersea cables in the Red Sea. Several were cut, possibly by a ship attacked by the Houthis dragging its anchor, but the rebels denied being responsible. On Sunday morning, the Houthis' al-Masirah satellite news channel acknowledged that the cuts had taken place, citing NetBlocks.
Moammar al-Eryani, the information minister with Yemen’s internationally recognized government that opposes the Houthis and is based in southern Yemen, issued a statement saying the cable cuts “cannot be isolated from the series of direct attacks carried out by the Houthi militia.”
“What is happening today in the Red Sea should serve as a wake-up call for the international community, which must take a firm stance to stop these escalating threats and protect the digital infrastructure that serves as the lifeline of the modern world,” al-Eryani said.
From November 2023 to December 2024, the Houthis targeted more than 100 ships with missiles and drones over the Israel-Hamas war in the Gaza Strip. In their campaign so far, the Houthis have sunk four vessels and killed at least eight mariners.
The Iranian-backed Houthis stopped their attacks during a brief ceasefire in the war. They later became the target of an intense weekslong campaign of airstrikes ordered by U.S. President Donald Trump before he declared a ceasefire had been reached with the rebels. The Houthis sank two vessels in July, killing at least four on board, with others believed to be held by the rebels.
The Houthis’ new attacks come as a new possible ceasefire in the Israel-Hamas war remains in the balance. Meanwhile, the future of talks between the U.S. and Iran over Tehran’s battered nuclear program is in question after Israel launched a 12-day war against the Islamic Republic in which the Americans bombed three Iranian atomic sites.
