Farouk Arnaz – Another homemade bomb was found in front of a church in Ambon on Monday, one day after a deadly blast in Solo and following two earlier explosions in the Maluku capital.

"This is in a series of bombs that we found there [in Ambon]," National Police spokesman Anton Bachrul Alam said on Monday. "The latest one today is in front of Maranatha church," Anton said. "All are homemade bombs, they are all similar. So the maker is the same."

On Thursday, a roadside bomb exploded in Karang Panjang, Ambon, according to police. That was followed by another blast on Saturday at the city's Mahardika terminal. No one was hurt in either explosion. Anton declined to speculate whether the bombs in Ambon were linked to the Solo suicide bomber.

However, the Jakarta Globe spoke to an anonymous source from the Anti-Terror Task Force who said that an early analysis appeared to link the attacks, and that they were revenge for the deadly sectarian violence that broke out in Ambon on Sept. 11.
