Militants launched a gun and bomb assault killing at least six people in the center of the Indonesian capital on Thursday, police said, in an attack that followed a threat by Islamic State fighters to put the country in their “spotlight”.Media said six bombs went off and a Reuters witness saw three dead people and a gunfight going on. One blast was in a Starbucks cafe and security forces were later seen entering the building.Police said they suspected a suicide bomber was responsible for at least one of the blasts and up to 14 militant gunmen were involved in the attack, Metro TV reported.”The Starbucks cafe windows are blown out. I see three dead people on the road. There has been a lull in the shooting but someone is on the roof of the building and police are aiming their guns at him,” said a Reuters photographer.Indonesia has been on edge in recent weeks over the threat posed by Islamist militants and counter-terrorism police have launched a crackdown on people with suspected links to Islamic State.”We have previously received a threat from Islamic State that Indonesia will be the spotlight,” police spokesman Anton Charliyan told reporters. But he said police did not know who was resposible. -
