At least three people were injured in a powerful explosion on Sunday near a railway station in Assam, the latest in a series of bombings and shootouts that have killed 77 people so far, officials said.
Police said the blast took place near the parking lot of the main railway station in New Bongaigaon, about 210 km west of Guwahati.
"Three people were wounded. Casualties would have been much higher had the bomb exploded a few metres away," a police official said over the telephone. The injured were shifted to a hospital.
On Saturday, two explosions and a shootout left three people dead and 15 injured in eastern Assam.
Authorities have blamed the latest attacks on the outlawed United Liberation Front of Asom (ULFA), Assam's main separatist group. An ULFA commander told local newspapers that they would target government officials if New Delhi did not stop the military crackdown against the outfit that began on January 8.
There were two more explosions in Guwahati earlier this week that killed four people and wounded about 30. The fresh attacks come soon after a warning from the ULFA to migrant Hindi-speaking workers to quit the region.
ULFA is one of several separatist outfits in Assam. Authorities have blamed it for the January 5-8 attacks in which 73 people were killed - 61 of them Hindi-speaking migrant workers.
The group denied responsibility for the massacre and blamed security forces instead. But the claim has few takers.
