Kathmandu : At least six people were injured in a bomb explosion in southern Nepal, the latest in a series of blasts to hit the region, police said Friday.
The blast ripped through a public square in Sarlahi Bazar Thursday night, about 140 kilometres southeast of the Nepalese capital, police said.
"Six people were wounded by shrapnel and the condition of one of the injured is serious," Superintendent of Police Ghanananda Bhatta said.
Bhatta added that the blast was a result of a time bomb but said it was not clear who was behind the attack.
Police said they were investigating the latest incident.
At least half a dozen crude bombs exploded in the neighbouring regional town of Janakpur Tuesday, injuring two people.
Several regional groups, including those demanding independence for the southern Nepalese plains known as Terai, have been involved in violent activities in the region since the beginning of the year.
Southern and southeastern Terai have seen some of the worst violence since the Maoists gave up their armed insurgency in 2006.
Since January, more than 65 people have died in clashes with police and fighting among rival political groups vying for influence in the region.
Several attempts by the government to bring the agitating groups to a negotiated settlement of the crisis have failed.
