BBC News reports rights groups have expressed concern for the large numbers of civilians trapped in the Afghan city of Kunduz, amid fierce fighting between the Taliban and government troops. The government has accused the Taliban of raping and killing civilians after it seized the northern city this week. The Taliban rejected the accusations. Both sides are claiming to be in control of much of the city. Kunduz was the first major urban center to fall to the Taliban in 14 years. In another development on Friday, the Taliban captured Baharak district in neighbouring Badakhshan province. Baharak is only 40km (24 miles) from the provincial capital Faizabad.
