Five people were killed and 25 others were wounded Sunday when three bombs exploded in India's restive northeast.
A local police official said two blasts went off within minutes of each other outside a police station in Nalbari town near the Assam state capital Gauhati.
The official, speaking on condition of anonymity as he is not authorized to speak to the media, said about five minutes later a third blast occurred a few miles (kilometers) away.
Assam's Inspector General of police Bhaskar Mahanta said authorities suspected the separatist group United Liberation Front of Asom as being behind the blasts.
No group claimed responsibility.
