JAKARTA A small explosion on Tuesday hit the Jakarta office of the Liberal Islamic Network, an Indonesian group that has defended the rights of minority Islamic sect Ahmadi, a witness said.
The explosion, which injured three people, comes a month after a mob beat to death three followers of the Ahmadi sect, considered heretical by mainstream Muslims.
Indonesia has won praise for largely defeating Islamic terror, but a recent spike in religious intolerance could heighten risk concerns for foreign investors counting on improved stability in Southeast Asia's largest economy and the world's most populous Muslim nation.
Ade Wahyudi, a manager at KBR68H radio that shares the office with the pluralist Liberal Islamic Network, said the office had called police to open a package that contained a book with wires sticking out of it. The police officer who opened the package was among the injured.
"I was on a different room, upstairs, and heard a bang, like thunder," Wahyudi told Reuters by telephone.
Indonesian authorities have said they are investigating last month's brutal mob killing, but human rights activists say authorities have not taken a strong stance against attacks on Ahmadis in the past.
Rights activists and several parliamentarians said on Tuesday that military personnel in western Java island recently summoned Ahmadi leaders to identify Ahmadi followers in their area and asked them to return to mainstream Islam.
"This goes to show a strengthening movement in government institutions trying to persecute Ahmadis. This is a worrying turn," said Haris Azhar of local rights group Kontras.
Military leaders denied the allegations of attempts at forced conversions.
Eva Kusuma Sundari, a member of the parliamentary legal commission from opposition party PDI-P, said the government should clarify the "disturbing" reports.
"It's deeply concerning. It reminds us of the past when the military was meddling into local politics and public order," she told Reuters by telephone.
