Birgunj, Oct 03 (ANI): Still piecing lives together from the worst earthquakes in 75 years, Nepalis are being tested by another trial - weeks of protests against a new Constitution have led to a shortage of essential commodities. The Madhesi community in Nepal's lowlands, many of whom trace their origins to India, have imposed an economic blockade to oppose the promulgation of the new Constitution. They are against splitting Nepal into seven provinces according to the new Constitution. Protesters are blocking up to 4,000 trucks at the border with India, the main supply route into landlocked Nepal, while the road to China is still obstructed by landslides. Nepal has started rationing fuel for vehicles, said Nepal Oil Corp spokesman Deepak Baral, after halt at crossing points on the India-Nepal border. More than 40 people have been killed in protests in the Himalayan republic since August. Indian oil trucks stopped crossing into Nepal because of protests in the south, prompting authorities to try to limit the use of cars and save fuel.As government talks with opposition parties stalled, traffic at the border with India remained stalled.
