Manila blast kills at least three, injures 23: A bomb ripped

Manila blast kills at least three, injures 23: A bomb ripped through a bus in suburban Manila late Friday, killing at least three people and injuring 23 others, hours after a grenade blast in the capital's financial district and a day after two deadly bombings in the southern Philippines. There was no immediate claim of responsibility for the bus blast. The bus explosion took place at 10 p.m. on the EDSA highway, one of the capital's main thoroughfares, in Quezon City, despite tightened security following the earlier attacks. -- AP
