Gunmen shot dead four people at Manila airport in the Philippines on Friday.
Labangan mayor Ukol Talumpa and three others were hit while waiting outside the airport terminal.
Airport manager Jose Angel Honrado said the gunmen shot them at close range. Four other people were reportedly wounded.
The Philippine Star newspaper reported police were considering political rivalry as a possible motive.
The BBC reports Mr Talumpa had survived two previous attacks: an ambush in 2010 and a grenade in 2012.
