A UN diplomat has warned that if the violence in Syria continues at its present rate, there is a “risk of genocide”.

Mokhtar Lamani, who worked with the UN during both the Balkans war and Rwanda, told the BBC that Alawites and Christians were at most risk, and that over two million Syrians have fled.

The BBC’s Middle East Editor Jeremy Bowen says UN envoys are reluctant to use the word “genocide” and that Lamani, based on the diplomat’s personal experience, can be considered an “authoritative source”.
