Syrian activist: 'Snipers are shooting everything that moves'

The UN Secretary General, Ban Ki-moon, has said the situation in Syria appears to be calmer after a ceasefire came into effect.

The truce is part of a peace plan negotiated by the special envoy, Kofi Annan.

But activists claim it is being only partially observed, and both sides are reporting violations.

Syrian activist Abu Abdo Alhomsy told the BBC that the humanitarian situation is catastrophic.
