(VOVWORLD) - A "massive" manhunt is underway for the attackers who bombed a Catholic Mass that killed four people in the southern Philippines, a senior military officer said on Monday, vowing to do everything possible to bring the perpetrators to justice.
Police are looking into at least two suspects they believe were behind the blast, which Islamic State militants claimed.
The bomb went off on Sunday during a service at a university gymnasium in Marawi, a city left in ruins in 2017 by a five-month military campaign to end an occupation by Islamic State loyalists that had triggered alarm across Asia.
The United States condemned the "horrific terrorist attack" and said it stood with Filipinos in rejecting violence, joining a chorus of support from countries including Japan, Australia, Britain, China and Canada.
