Moni, and Tanjim Ahmad Sohel Taj, son of Tajuddin Ahmad. Since 2009, the Awami League government faced several major political challenges, including BDR (border security force) mutiny, power crisis, unrest in garments industry and stock market fluctuations. Judicial achievements for the party included restoring 1972 constitution (set by the first Awami League government), beginning of war crimes trials, and guilty verdict in 1975 assassination trial. According to the Nielsen 2-year survey, 50% felt the country was moving in the right direction, and 36% gave the government a favourable rating. Bangladesh Rifles revolt On 25 and 26 February 2009, section of the Bangladesh Rifles (BDR), a paramilitary force mainly tasked with guarding the borders of Bangladesh, staged a mutiny that brought the national life to a standstill. The rebelling BDR soldiers took over the BDR headquarters in Pilkhana, killing the BDR Director-General and some army officers. They also fired on civilians, held many of their officers hostage, vandalised property and looted valuables. By the second day, unrest had spread to 12 other towns and cities. Eventually, a total of seventy-four people were killed. Among them were 57 army officers seconded to the BDR. The Chief of the BDR, the Deputy Chief and all 16 Sector Commanders died during the revolt. The mutiny ended as the mutineers surrendered their arms and released the hostages after a series of discussions and negotiations with the government. Administrative divisions Throughout the decade Bangladesh was administratively divided into 6 divisions, namely Dhaka, Chittagong, Khulna, Rajshahi, Barisal and Sylhet which were further subdivided into a total of 64 districts (See List of districts of Bangladesh). Demographics Based on World Development Indicators published by the World Bank the population of Bangladesh grew from 129 million at the beginning of the decade to 150 million by the end. This signifies an annual population growth rate of 1.5%. Population density increased from 991 to 1156 per km2. The urban population was 23.6% of the total at the beginning, which ended up at 29.7%. Dhaka, the largest city, with a population of 10.3 million, accounted for 33.1% of the total urban population by 2009. United Nations World Population Prospects show that the population growth rate was in decreasing trend (from 2.0% per annum to 1.1%), primarily due to reduction in fertility rate (births per woman) from 3.2 to 2.4. Life expectancy at birth increased from 65.3 years to 69.8 years with
