United Nations inspectors were shot at who are in Syria to investigate alleged use of chemical weapons in last week's attack in Damascus suburb of Mouadamiya in which nearly 1000's were killed.
The attack comes after the West's threatened bomb attack against Syria.
According to the Mirror, after finally getting the go-ahead to move in, UN experts came under fire looking for evidence of sarin nerve agent.
A UN statement said the lead vehicle was deliberately shot at multiple times by unidentified gunmen in a buffer zone between rebel and government territory.
The 4x4 was forced back to the UN's hotel in central Damascus and the attack delayed the experts' work, meaning they could only visit six of 12 sites on their itinerary, the report added.
