Amazon cloud unit’s data centres in Bahrain and the United Arab Emirates (UAE) faced connectivity issues on Monday, the company said, amid retaliatory Iranian strikes in the region in response to strikes by the United States and Israel on the Islamic Republic.

Iranian strikes have hit airports, ports, and residential areas across the wider Gulf.

One of the cloud unit AWS’ zones in the UAE was still without power on Monday, after the company said that “objects” struck the data centre and created sparks and fire.

Amazon reported some recovery in the UAE but recommended that customers use alternate regions as it investigates “additional connectivity issues and error rates.” The company did not confirm or deny, when asked earlier, whether the UAE data centre incident was connected to the Iranian strikes.

Amazon did not provide a reason for the connectivity issues at its Bahrain data centre. It also did not respond to a Reuters request for comment.

Meanwhile, Israel launched new air strikes targeting Tehran and expanded its military campaign to include attacks on Iran-backed Hezbollah fighters in Lebanon on Monday, as US President Donald Trump signalled the US-Israeli military assault on Iranian targets could continue for weeks.

Israel said it was attacking sites connected to Lebanon’s Shia Muslim armed group Hezbollah, one of Tehran’s principal allies in the Middle East, after Hezbollah acknowledged launching missiles and drones toward Israel in retaliation for the killing of Iran’s Supreme Leader Ayatollah Ali Khamenei.

Iran pledged retaliation following the assassination, with authorities quickly forming an interim leadership structure to guide the country through the ongoing crisis. State media described the assassination as a defining attack on the Islamic Republic’s political and religious leadership.

President Masoud Pezeshkian declared that avenging Khamenei’s death was both “a duty and a right of the nation”. Iran’s state media subsequently announced on Monday that a new wave of missiles is being launched from central parts of Iran towards “enemy locations”.
