At least two people have been killed and four others wounded in a grenade attack on a mosque in the southern Philippines, local officials say.
The attack in Zamboanga city took place in the early hours of Wednesday, just days after deadly twins in a Roman Catholic cathedral on a nearby island and a voice supporting a wider Muslim autonomy in Mindanao, the country's volatile southern region.
"A grenade was stumbled inside a mosque that killed two people and injured another four," said regional military spokesman, Shutterman Gerry Besana, to the AFP news agency for the Zamboanga attack.
The victims were allegedly sleeping inside the mosque at the time of attack, which immediately condemned local officials [1
"We encourage people of all faiths … to come together to pray for peace."
The Ulama Council of the Zamboanga Peninsula condemned what it called a "devilish, irrational and inhuman action" and urged people to be vigilant.  There were no immediate claims for damages.
The military called for agreement among Mindanao communities and urged the public to refrain from speculation on social media that could spread misinformation.
Regional task force commander Colonel Leonel Nicolas stressed the incident was "not a recurring act" for the church bombing three days before.
The country was alerted to two explosions during a Sunday church service at Our Lady Cathedral of Mount Carmel in Jolo town, Sulu province, killing at least 21 people and wounding more than 100 others
The Islamic State of Iraq and The Levant (ISIL, also known as the ISIS) group claimed responsibility for the cathedral blast, one of the worst cases of violence in the Philippines restive south.
President Rodrigo Duterte owed Abu Sayyaf, a domestic armed group who has promised faith in ISIL and has carried out bombings, kidnappings and beheading in Mindanao to carry out the church bombing.  "No one, but no one, could continue this kind of terrorism in this area," he said this week during a visit to the region.
