The deputy prime minister of fuel-starved Nepal says Indian officials have assured him of increased supplies.

Kamal Thapa returned home Monday after meeting in India with Prime Minister Narendra Modi and External Affairs Minister Sushma Swaraj.

Ethnic Madhesi protesters in southern Nepal have been protesting against the makeup of states created by the country's new constitution by blocking a key border crossing with India, which supplies nearly all of Nepal's fuel.

Thapa said the Indian leaders promised that fuel trucks lined up at the crossing would be rerouted and more fuel would be supplied through other border points to ease the shortage in Nepal.

India, which has close cultural ties with ethnic Madhesi, has expressed unhappiness over the constitution.
