A series of apparently synchronized explosions tore through four towns in the troubled state of Assam in northeastern India on Thursday, killing at least 67 people and leaving more than 210 wounded, according to witnesses and police.
The bombs targeted crowded markets and government buildings like courts and police stations, witnesses said. The attacks, among the bloodiest in recent months, left streets littered with bodies and the wreckage of cars and motorcycles, according to witnesses and photographers at the scene.
There were no immediate reports that any group had taken responsibility.
For many years, Assam state has been riven by a separatist insurgency led by the United Liberation Front of Assam, which demands independence for the region of some 26 million people and is often blamed for bombings. Last month, ethnic clashes left 57 people dead in the area when indigenous Bodos fought with Bengali-speaking Muslims.
Witnesses and police said at least nine blasts rocked the four towns attacked on Thursday, including three in the state capital, Guwahati, where one bomb had been left in the parking lot of the district court.
Khagen Sharma, police inspector general in Assam state, said authorities suspected the attacks may have been orchestrated by the United Liberation Front of Assam working with militant jihadist groups. He said the police had been on high alert after tips of an attack.
The blasts were the latest bombings in several parts of India as national elections approach. Before Thursday's explosions, about 150 people had died in seven recent attacks around the country.
