Nepal is considering rationing oil and fuel, a Nepal Oil Corp spokesman said yesterday, after hundreds of trucks were held up this week at the India border when protesters against a new constitution gathered to block the road. Nepal adopted the charter last Sunday to promote unity and stability after years of civil war, but its demarcation of provinces has upset people in Nepal's south who fear the new federal structure will marginalise them. At least 40 people, mostly protestors, have been killed in violent clashes since August. About 900 trucks carrying food, fuel and other items were lined up on the Indian side of the Raxaul-Birgunj border yesterday.
