Two bombs minutes apart tore through a Roman Catholic cathedral on a southern Philippine island where Muslim militants are active, killing at least 27 people and wounding 77 others during a Sunday Mass, officials said.
Witnesses said the first blast inside the Jolo cathedral in the provincial capital sent churchgoers, some of them wounded, to stampede out of the main door.
Army troops and police posted outside were rushing in when the second bomb went off about one minute later near the main entrance, causing more deaths and injuries. The military was checking a report that the second explosive device may have been attached to a parked motorcycle.
The initial explosion scattered the wooden pews inside the main hall and blasted window glass panels, and the second bomb hurled human remains and debris across a town square fronting the Cathedral of Our Lady of Mount Carmel, witnesses said.
Cellphone signal was cut off in the first hours after the attack. The witnesses who spoke to The Associated Press refused to give their names or were busy at the scene of the blasts.
Police said at least 27 people died and 77 were wounded. The fatalities included 20 civilians and seven troops. Among the wounded were 14 troops, two police and 61 civilians.
Troops in armoured carriers sealed off the main road leading to the church while vehicles transported the dead and wounded to the town hospital. Some casualties were evacuated by air to nearby Zamboanga city.
