Several injured as Saudi capital airport reportedly hit again

Several people have been injured in an attack on an international airport in the Saudi capital, reports say, just days after Yemen's Houthi rebels claimed two successful attacks on the hub.

The attack comes a day after authorities said three Saudi nationals, including a pilot, were killed in two attacks by the Iran-backed Houthis the day prior.

The suspected attack comes during a marked escalation in renewed fighting between Yemen's Saudi-backed government forces and the Houthis, who control most of the country's north-west.
