The attack killed at least 12 people and injured 309 at last count, say Saudi officials. The dead include four Saudi citizens, two Bangladeshi nationals, a Palestinian, a US citizen, an Egyptian, a Jordanian, a Syrian and a Sudanese.

Good morning and welcome to our live coverage of rapidly unfolding events in the Middle East.

After attacking Saudi Arabia’s main international airport on Saturday in strikes which killed at least 12 people and injured 309, the Houthis have issued another message this morning about the kingdom’s airports.

In response to the Houthi’s assault – the deadliest in Saudi Arabia in over a decade – US President Donald Trump has said Washington may join the Saudis in carrying out air strikes against the Iran-backed group in Yemen. Trump said: “We may. We’re going to look at it. We just found out about the recent attack, so we’ll make a decision. We move very quickly.”
