JAKARTA, Indonesia – A suicide bomber blew himself up as police were praying Friday, wounding 28 people in the first attack on a mosque since extremists started targeting the predominantly Muslim country a decade ago. Though houses of worship are commonly targeted by militants in Afghanistan, Pakistan and Iraq, the attack in the West Java town of Cirebon was a first for Indonesia. Even former Jemaah Islamiyah members were outraged. "To attack Muslims as their performing Friday prayers?!" said Abu Ghifari, who quit the group because he disagreed with some of its doctrines. "It's a great sin!"
