Violent protests against a proposed new Constitution intensified in Nepal's southern plains on Wednesday with demonstrators attacking police, who shot dead at least four people, officers said.
Nepal is in the final stages of preparing a new Constitution that would carve the country into seven federal provinces.
Many people in Nepal's southern plains oppose the plan, which would split their narrow region and merge the pieces into larger provinces with other ethnic groups.
Thirty people have now been killed since the draft Constitution was unveiled in August.
Three demonstrators were shot in the town of Jaleswor in Mahottari district, 100 km southeast of Kathmandu, after a police post was attacked by thousands of protesters armed with sticks and stones, police official Saurav Rana said.
Hundreds of demonstrators armed with catapults clashed with police in the nearby Saptari district, where a fourth protester was shot dead, police official Sisir Karmacharya said.
