Grenade hurled at cathedral in southern Philippines

Asian Defense News: ZAMBOANGA, Philippines (AFP) - – A grenade went off on Sunday outside a Catholic cathedral on a southern Philippine island which has seen bloody Muslim extremist attacks in recent years, the military said.
Unidentified men hurled the grenade before dawn in Jolo island's capital town of Jolos, said Brigadier General Rustico Guerrero, head of an anti-terrorism task force.
The blast shattered some cathedral windows but no one was injured.
Previous grenade explosions in the area have been blamed on the Abu Sayyaf, a Muslim extremist group linked by intelligence agencies to the Al-Qaeda network.
However, Guerrero said there were no immediate suspects in the latest blast.
Jolo, a Muslim-dominated island with a Christian minority, has long been a haunt of the Abu Sayyaf who are blamed for the worst terror attacks in Philippine history.
In September, two US soldiers who were training local forces against the Abu Sayyaf were killed by a roadside bomb planted by extremists on Jolo island.
