"I was reaching for my coffee when I heard the thump," writes Jakarta-based photographer Bay Ismoyo. "It didn’t sound like a blast. More like a heavy metal part falling to the ground. I thought it was a crash between cars, or something falling from the roof. So I left the coffee on the counter and ran outside."

"I have to confess that I’m still shocked to have seen this. It’s the first time that I see a gunfight between police and terrorists right in front of me like this, so close. And it was in downtown! It’s the heart of my city, very close to the palace, to the embassies. It shakes you up."
