Syria unrest: Maps and videos of Homs fighting
Opposition and human rights activists say an estimated 700 people have been killed in Homs since rockets and mortars began hitting homes in the city's opposition-dominated districts on 4 February. Tanks and troops entered the protest centre of Baba Amr on 1 March after the rebel Free Syrian Army announced a "tactical withdrawal".
Homs has been a focus of anti-government unrest since demonstrations against President Bashar al-Assad erupted in March 2011. The UN says more than 7,500 people have been killed by security forces across the country. The government says at least 1,345 members of the security forces have been killed combating what it calls "armed gangs and terrorists", and puts the number of civilians killed at 2,493.
