City of Homs shelled as advance UN team of observers arrives in Damascus to reinforce Annan's six-point peace plan.
The first international observers tasked with monitoring a tenuous United Nations-backed ceasefire have arrived in Syria, where activists said government forces were continuing to attack opposition neighbourhoods.
The Syrian government said that it would not be responsible for the safety of the monitors, however, unless it was involved in "all steps on the ground", Bouthaina Shaaban, a spokesperson and presidential adviser, said.
She said Syria reserved the right to agree on the nationality of those participating in the mission.
Government forces on Sunday subjected the Khalidiyeh and Bayada neighbourhoods of Homs to fierce bombardment, despite the fact that both the government and opposition had agreed to a ceasefire that came into effect at dawn on Thursday.
