Syria crisis: Brahimi warns horror is 'unprecedented'

The conflict in Syria has reached "unprecedented levels of horror", peace envoy Lakhdar Brahimi has told the UN Security Council.

The UN-Arab League envoy said Syria was being destroyed "bit by bit" with grave consequences for the wider region.

He was speaking hours after evidence emerged of a fresh massacre in the northern city of Aleppo.

At least 71 bodies were found by a river in the western Bustan al-Qasr district, opposition activists said.

Most had their hands tied behind their backs and gunshot wounds to the head.

Mr Brahimi has been trying to find a solution to the crisis based on a peace plan approved at an international conference in June 2012.

The UN says the conflict has left more than 60,000 people dead.

Speaking later to reporters, Mr Brahimi said the Syrian government and the opposition were, between them, destroying Syria "bit by bit".

"The region is being pushed into a situation that is extremely bad," he said.

"That is why I believe the Security Council simply cannot continue to say: 'We are in disagreement, therefore let's wait for better times.' I think they have to grapple with this problem now."The bodies were caked in mud and showed signs of rigor mortis. There were also signs of blood having poured from many of the heads.

The government and opposition have blamed each other for the killings.

The district of Bustan al-Qasr has been hotly contested since fighting broke out in Aleppo last July, correspondents say.
