SURABAYA, Indonesia (Reuters) - A suicide bomber on a motorbike wounded several Indonesian police outside a police building in Surabaya on Monday, a day after Islamist militants launched suicide attacks on churches in the country's second largest city, police said.

"Clearly it’s a suicide bombing," East Java police spokesman Frans Barung Mangera said.
