A grenade attack has killed four people and injured around 15 others at a store in Jolo, an area in the southwest Philippines.
The incident happened on the island of Jolo, capital of the Sulu province, when a grenade was thrown near a bakery on Saturday evening.
Four people perished and scores more were wounded in the explosion, which, according to daily newspaper the Philstar, is suspected of being part of an escape attempt by a fleeing robber.
However, the Northbound Philippines News Online report that the blast may be in retaliation to a shooting in which a child injured on Friday.
A man has reportedly been arrested over the explosion and police have not yet commented on potential reasons for the attack.
“A suspect was arrested and [is] now in the custody of Jolo Municipal Police Station. Motive is still unknown,” said Col Cirilito Sobejana, commander of a Sulu military task force.
