MANILA, Philippines — A bus carrying supporters of a local politician fell off a cliff in the mountainous northern Philippines on Saturday, killing 12 people, a police spokesman said.

The victims were supporters of the mayor of the town of Buguias, Melchor Diclas, and were being ferried home from a victory party he hosted after he retained his post in last month's elections, police said.

Rescuers found 10 bodies at the bottom of a 262-foot ravine and two others were declared dead on arrival at nearby hospitals.

Seven passengers were treated for injuries, said local police spokesman Vicente Lim-mong
