Suspected militants hurled a grenade inside a Roman Catholic Church on Tuesday in the southern Philippines but there were no casualties in the attack.
Regional police director Chief Superintendent Paisal Umpa told reporters there were no casualties in the blast shortly before 11: 00 inside the church along Arolas Street in Jolo, Sulu.
Investigators said the explosive was lobbed from overland terminal beside the church.
No group claimed responsibility for the attack but Philippine troops blamed militants belonging to the Abu Sayyaf group as behind in previous terror attacks.
Jolo is a known bailiwick of Abu Sayyaf, a group blacklisted by Washington as a foreign terrorist organization.
The group is considered a major security threat to the Philippines and the region engaged in kidnappings, bombings and even beheadings in the South over the past decade.
A day before the incident, security forces have foiled a roadside bombing in Zamboanga del Norte following the recovery of improvised bombs
planted by unknown suspects.
On July 5, six people died and over 50 were injured when a homemade bomb went off in front of a Catholic church here.
