A civilian plane was set alight when Yemen's Huthi rebels attacked an airport in southern Saudi Arabia, the Riyadh-led coalition battling the insurgents said Wednesday. "A cowardly terrorist attack by the Huthi militia on Abha international airport... A civilian plane within the airport grounds was exposed to a fire which was brought under control," state-run Al-Ekhbariya television cited the coalition as saying. bur-sy-ac/sls/par
