UN fears century's 'worst' crisis in Syria

President Bashar al-Assad has now set his sights on Idlib, and his forces have stepped up bombardment of the densely populated province since the beginning of the month.

That has prompted an estimated 30,452 people to be displaced within Idlib and parts of adjacent Hama province between September 1 and 9, the UN's humanitarian coordination agency (OCHA) said Monday.

"We're deeply concerned about this recent escalation of violence, which has resulted in the displacement of over 30,000 in the area. That's something we're monitoring very closely," OCHA spokesman David Swanson told AFP.

The conflict's three powerbrokers -- regime allies Russia and Iran and rebel backer Turkey -- agreed at a summit last week to "stabilise" Idlib, but few details emerged on how they would do it. Delegations from the three countries will be in Geneva on Tuesday to meet the UN's Syria envoy Staffan de Mistura.
