At least one person was killed and eight wounded in two separate explosions on Sunday in Assam, officials said.
A police spokesman said a powerful blast took place around 6.00 pm near a crowded vegetable market near Bahari village in Barpeta district, about 160 km from Assam's main city of Guwahati.
"A cobbler who was working near the market died on the spot, while five people were injured in the attack," police official A Ali said.
The condition of two of the injured was stated to be critical.
"The injured with multiple wounds were shifted to a hospital," the official said.
Earlier on Sunday, three people were injured in a blast that took place near the parking lot of the main railway station in New Bongaigaon, about 210 km west of Guwahati.
"The bomb was kept on a parked motorcycle," a police official said.
Sunday's attacks were the latest in a string of bombings in the state blamed on the outlawed United Liberation Front of Asom (ULFA), a rebel group fighting for an independent homeland.
On Saturday, three people, including a government official, were killed and 15 injured in two explosions and a shootout in eastern Assam. Two explosions in Guwahati last week killed four people and wounded 30.
A man claiming to be an ULFA commander told local newspapers by telephone that the outfit would attack government officials if New Delhi did not stop a military crackdown against it that began on January 8.
The attacks came soon after a warning from the ULFA to migrant Hindi-speaking workers to quit the region. ULFA is one of several separatist rebel outfits operating in Assam where at least 20,000 people have died in insurgency-related violence since 1979.
It has been blamed for a wave of attacks in the oil and tea-rich state during January 5-8 killing 73 people - 61 of them Hindi-speaking migrant workers.
