A family of five riding two motorbikes carried out a suicide bombing in the Indonesian city of Surabaya Monday, one day after another family carried out bomb attacks on three churches in the same city. Video footage of the latest attack on police headquarters shows two motorbikes approaching a checkpoint just before the blast. Six civilians and four police officers were injured, the authorities say, and an eight-year-old daughter survived the suicide attack. The girl was wedged between her mother and father on the motorbike as they carried out the attack. Police blamed Sunday's attack on an Islamic State-inspired network. That attack killed 13 people, not including the family of six who carried out the bombing.
