Billionaire Elon Musk on Saturday said that his Starlink satellite service would support internet access for "internationally recognized aid organizations in Gaza," which have faced a telecommunications blackout since Friday.

Starlink is a network of satellites in low Earth orbit that can provide internet to remote locations, or areas that have had normal communications infrastructure disabled.

Musk, who owns Starlink operator SpaceX, was responding to a post by US Democrat congresswoman Alexandria Ocasio-Cortez in which she called the communications blackout in Gaza "unacceptable".

"Starlink will support connectivity to internationally recognized aid organizations in Gaza," Musk wrote on X, formerly Twitter, which he also owns.

Israel unleashed its bombing campaign after Hamas gunmen stormed across the Gaza border on 7 October, killing 1,400 people, mostly civilians, and seizing more than 220 hostages, according to Israeli officials.

The health ministry in the Hamas-run Gaza said Israeli strikes had killed 7,703 people, mainly civilians, including more than 3,500 children.

Musk's Starlink satellite internet service was also deployed in Ukraine shortly after the Russian invasion in February 2022. 

The network, which helps increasingly high-tech soldiers to operate in areas where other means of communication are down, is a key battlefield tool for Kyiv.

In September, the US tech billionaire Elon Musk said he had prevented Ukraine from wiping out Russia's Black Sea navy fleet last year by denying Starlink internet access.

"There was an emergency request from government authorities to activate Starlink to Sevastopol. The obvious intent being to sink most of the Russian fleet at anchor," Musk wrote on X.

The statement sparked sharp condemnation from Mykhailo Podolyak, a senior aide to Ukrainian President Volodymyr Zelensky.
