On Friday Turkey's President, Recep Tayyip Erdogan, held a summit with Russia's Vladmir Putin and Hassan Rouhani of Iran, the other key ally of the Syrian leader, Bashar al-Assad, and urged them to accept a truce to avert a "bloodbath".

"A regime assault [in Idlib] would also create serious humanitarian and security risks for Turkey, the rest of Europe and beyond", he added.

In an article in today's Wall Street Journal, he calls on the global community to take action, and warns that "the entire world stands to pay the price" otherwise. "To ensure that we succeed, the rest of the world must set aside narrow self-interest and throw its weight behind a political solution", he said.
Idlib is the last rebel stronghold - if the regime wins here it will have effectively won the Syrian war and defeated the revolution.
