A man armed with a bomb and an ax intended to wreak havoc during a packed Sunday Mass celebration in Indonesia, but his bomb burst into flames rather than explode. Police told local media that the man was carrying items marked with an Islamic State insignia.

The attacker did manage to swing his axe at the church's 60-year-old priest, slightly injuring his hand. Congregants were able to subdue the attacker until police arrived.

Indonesia is home to more Muslims than any other country. Almost all of its roughly 250 million people are moderate Sunni Muslims, though there is a significant Christian minority. Compared with other large Muslim countries, militancy is relatively rare in Indonesia, though extremist groups have carried out minor attacks, including of churches.

The biggest attack in the country occurred in 2002 when terrorists bombed nightclubs on the island of Bali, killing 202, including 88 Australians. Since then, the government has sustained a massive crackdown on militant cells.
