A new airstrike on Friday struck the capital of Yemen, Sana’a, just a day after Israeli warplanes targeted key sites in Yemen to disrupt Houthi military operations, including their entry points from Iran.

The Iran-backed Houthi militants have blamed the US and Britain for the new attack. There has been no immediate comment from the US, Britain, or Israel.

An armed Shi'ite movement which controls most of northern Yemen, the Houthis are armed by Iran and part of its so-called Axis of Resistance against Israel.

After killing the top leaders and destroying the assets of other Iran-backed militant groups like Hezbollah and Hamas, Israel is now preparing for a new front against the Houthis in Yemen, which it calls "the last man standing" among Iran's armed allies, after rebels toppled Iran's key ally Syrian President Bashar al-Assad.

Israeli Prime Minister Benjamin Netanyahu announced Thursday that the fight against the Houthis “is only getting started.”
