The leader of Yemen's Iran-aligned Houthis, Abdul Malik al-Houthi, said on Thursday his group will monitor the implementation of a ceasefire deal between Israel and Hamas aimed at ending the 15-month war in Gaza and continue its attacks if it is breached.

Tens of thousands of Yemenis joined a demonstration in Sanaa to show solidarity with Palestinians in the Gaza Strip, where smoke could be seen from Israeli strikes against Houthi rebel targets. Israel's Defense Minister said the airstrikes in Yemen were a clear message to Houthi leader Abdul-Malik al-Houthi.

Analysis: Yemen is an escalating frontline in Israel's proxy war with Iran, but Tel Aviv may struggle to achieve a military triumph against the Houthis.

The Israeli military on Saturday said it intercepted a rocket from Yemen, one day before a ceasefire with the Palestinian militant group Hamas is set to take effect. Residents rushed to shelters as alerts sounded in Tel Aviv and other parts of Israel.

Israel, the US and Britain carried out dozens of airstrikes across Yemen on Friday, amid rising escalation between the Houthis and Tel Aviv over the Gaza war.
