MIDSAYAP, Philippines, Oct. 3 (UPI) -- A man threw a grenade into a mosque in the Philippines Friday, killing four people and wounding at least 17.
The attack, in the town of Midsayap in the southern Philippines, is believed to have been motivated by a personal feud rather than religious hatred, the London Telegraph reported.
The mosque was within the compound of the government's National Irrigation Administration and was full of staff attending a weekly prayer meeting.
One of the dead was the director of the local irrigation administration office.
Provincial Gov. Emmanuel Pinol said the attack was due to an internal dispute within the irrigation administration over who would head the office.
Police are searching for two people seen standing outside the mosque shortly before the blast.
