Maoists cadres carrying sticks and red banners blocked all approach roads leading to the country's key administrative building complex. The strike is aimed to topple the Madhav Kumar Nepal led 22-party coalition government. Talking tough, Maoists former guerrilla turned party chief Prachanda warned that they did not intend to relent and asked his cadres to further intensify the protest. Hundreds of tourists including foreign nationals remained stranded in the city-centre as the Maoists did not allow the public transport to ply. Food stocks and medicines are also running low in the city though the authorities manage to sneak in some essential supplies in truck convoys escorted by armed policemen. Meanwhile, Home Minister Bhim Rawal told media persons that the government is trying to resume supply of essential goods such as medicine, cooking gas, food grains, and vegetables in Kathmandu by providing security escort in coordination with traders.
