JAKARTA (AFP/BLOOMBERG) - Starbucks is closing all of its Jakarta branches "until further notice", the global coffee giant said after one of its stores in the Indonesian capital was hit by apparent suicide attacks on Thursday.

"This store and all other Starbucks stores in Jakarta will remain closed, out of an abundance of caution, until further notice. We are monitoring this situation closely," the company said in a statement.

There were no customer or staff fatalities, Chief Executive Officer Howard Schultz said in Mumbai.

"We are living in a time of great uncertainty and fragile nature," Schultz said.

"This is a senseless act of violence and terrorism that many of us cannot process."

Explosions ripped through central Jakarta, killing several people in the worst attack in the Indonesian capital since 2009.

At least six blasts occurred near the Sarinah shopping centre, close to the United Nations office, one of which targeted a police post.
