Houthi forces appear to make slow advance in south-west Yemen

Group's fighters hit key airport in Aden with explosive moments before plane from Cairo was due to land

Houthi forces appeared to be making slow advances on Wednesday in south-west Yemen, approaching the city of Taiz and firing a missile and an explosive towards the airport in Aden, the chief international hub of the Saudi-backed government.

The explosive hit the key airport moments before a plane was due to land. The British ambassador to Yemen, Abda Sharif, said the attack could have endangered thousands of people. It forced the flight - from Cairo - to be diverted to Jeddah and led to a review about the safety of flights in Aden.
