The conflict in Syria has claimed a heavy death toll. At least 60,000 people have now been killed in Syria according to the United Nations.
A key turning point in the conflict came with the brief fall of the Baba Amr district of the central city of Homs to opponents of President Assad.
The BBC's correspondent Paul Wood was in Baba Amr during the shelling and has met some of the Syrians whose lives changed dramatically as a result.
Many are now living in exile in neighbouring Lebanon.
