Jakarta, July 17 (Xinhua) Two people were killed in another explosion in north Jakarta just two hours after blasts in two luxury hotels in the Indonesian capital killed at least six people Friday, reports said.

A bomb-laden car exploded at a freeway gate of Muara Angke of north Jakarta around 10.30 a.m., killing two people and injuring several others, local television channels reported.

'We have information that an explosion occurred there. We are deploying our officials to the location. However, we are still not sure what the source of the explosion is,' Vivi, an official at Jasa Marga, the freeway operator, told news portal detikcom.

The blast occurred following two major explosions in the JW Marriot Hotel and the Ritz Carlton Hotel in South Jakarta, killing at least six people and injuring 23 others.
