Police in Bangladesh have fired tear gas to disperse thousands of people protesting a lack of water and electricity. Some 100 people were injured, including 10 police officials. Police say the protesters had blocked a major highway connecting the capital, Dhaka, and the southern port city of Chittagong, and violence erupted when police tried to break up the mob. A local legislator tried to persuade the protesters to end their sit-in strike on the highway but he was chased away by the stone-throwing crowds. Most areas in Bangladesh including Dhaka, a city of 10 million people, are without power for several hours each day. There is also a shortage of clean drinking water in the country.
