The Iranian-backed Houthis have claimed a missile attack on Saudi Arabia, after Riyadh launched strikes on targets linked to the group on Friday. Early on Saturday, the Houthis' Ansarollah media said on Telegram that a "Yemeni missile strike" had caused fires in the Saudi city of Jizan. The group had vowed retaliation after Saudi Arabia launched air strikes on Houthi targets in the Yemeni port city of Hodeida and a nearby island on Friday. Earlier, a delegation from Oman arrived in Iran's capital Tehran for talks on the Strait of Hormuz, Iran's state-run IRNA news agency reported. The US and UK are set to hold a conference in London next week to discuss the Strait of Hormuz, the BBC understands.
