Israel is quickly running out of Iron Dome interceptor missiles, military analysts have warned.

The US is rapidly moving to plug gaps in its defences, including by deploying a terminal high-altitude area defence (Thaad) missile system to Israel.

But analysts warned this may not be enough as the US races to supply defensive weapons to both Israel and Ukraine.

“If Iran responds to an Israel attack [with a massive air strike campaign], and Hezbollah joins in too, Israel air defences will be stretched,” Dana Stroul, a former senior US defence official, told the Financial Times.

“The US can’t continue supplying Ukraine and Israel at the same pace. We are reaching a tipping point.”

It comes as Israel prepares to launch a retaliatory strike against Iran, which fired around 200 missiles at Israeli targets earlier this month.

US and Israeli officials believe the strike could risk further regional escalation, meaning they are racing to fill any gaps in the country’s defences.
