At least three people have been wounded after a bomb explodes at a building near Indonesia's capital, police officials say.
The explosion suspected to be a bomb workshop occurred on Saturday in a building listed as an orphanage in the town of Depok, a city in West Java Province on the outskirts of Jakarta.
"Three people were injured in the explosion, one of them had a broken arm and burns covering around 50 to 70 percent of his body," AFP quoted national police spokesman Anang Iskandar as saying on Sunday.
A big haul of bomb-making materials including grenades, detonators and potassium chlorate have been seized from the house, he added.
Earlier in the month, Indonesian police have shot dead two 19-year-old suspected terrorists in an armed clash that also left one policeman dead in the city of Solo in central Java.
