Gunmen in police uniforms shot dead a town mayor and three other people at the airport in the Philippine capital on Friday, sending travelers fleeing for safety, authorities said.
Ukol Talumpa was mayor of a town called Labangan, Zamboanga del Sur. Three passengers were also killed and four people were wounded, airport manager Jose Honrado said.
Talumpa was waiting for a ride with his family outside the airport terminal in Manila when the gunmen approached and shot him at close range, Honrado said.
"We are still investigating the motive," he said. The mayor's relatives declined to comment. The attackers escaped on a motorcycle.
Manila's Ninoy Aquino International Airport is named after prominent opposition politician Benigno Aqunio, who was shot dead there in 1983 as he arrived home from self exile.
His son, also Benigno Aqunio, is now president.
