An Indian man was killed when police in Nepal fired on hundreds of protesters blocking a border crossing with India.
Police were trying to clear the blockade, which has cut supply lines of fuel and other goods, when protesters attacked a police post at Birgunj.
Reports say the man was shot in the head and later died in hospital.
The demonstrators, mainly from southern lowland minority groups, are protesting against Nepal's new constitution, which they say marginalises them.
Since August, this has sparked clashes around Nepal leaving dozens dead.
The dead protester was identified as Ashish Kumar Ram, from Raxaul in the Indian state of Bihar, local officials said.
