Jakarta, Indonesia (CNN)Attackers struck in the middle of the day Thursday, in the middle of a busy central Jakarta commercial hub -- killing at least two, wounding 19 and raising alarms about terrorism once more, this time in the world's most populous Muslim country.
There was no immediate claim of responsibility for the rattle of shots and explosions from at least five attackers. But police believe that they were linked to ISIS, and the Islamic State-affiliated Aamaq News Agency reported people from that terror group were behind the bloodshed.
