On Friday, the Yemeni rebels warned they would keep up their attacks if Israel did not respect the terms of the ceasefire with Hamas, which is scheduled to begin at 0630 GMT Sunday.

The leader of Yemen's Houthis said on Thursday that the Iran-aligned group would monitor the implementation of a ceasefire deal between Israel and Hamas aimed at ending the war in Gaza and continue its attacks on vessels or Israel if it is breached.

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.

The Iranian-backed Houthis carried out two attacks on Israel on January 18, the eve of the ceasefire between Israel and Hamas. This is an important symbol of how the Houthis intend to show that they have not been deterred by Israel’s strikes and they are prepared to continue to attack Israel if the ceasefire falls apart.
