Russia and Turkey give more time for Idlib deal in Syria: UN

Russia and Turkey plan to give more time for the implementation of their de-escalation deal in the Syrian province of Idlib, a "great relief" for 3 million civilians in the area, U.N. humanitarian adviser Jan Egeland told reporters on Thursday.

But there were still "a million unanswered questions" about how the deal would work, and what would happen if groups designated as terrorists refused to lay down their weapons.

Speaking after a regular Syria humanitarian meeting in Geneva, Egeland said Syria's ally Russia had confirmed that Damascus had scrapped a "very concerning" law allowing the expropriation of land and property from refugees.

Idlib and adjacent areas are the last stronghold of the opposition who rose up against President Bashar al-Assad in 2011, and the U.N. has warned that a battle to restore Assad's control over the zone could be the worst of the seven-year-old war.

Turkey and Russia's deal set up a buffer zone running 15-20 km (9-13 miles) deep into opposition territory that originally had to be free of heavy weapons and jihadists by Monday.

"There will be more time for diplomacy," Egeland said.

"I was heartened to hear both Russia and Turkey say they are optimistic, they can achieve much more through negotiations, and they are generally very positive on the implementation of this deal which is giving a relief, a pause in fighting, to Idlib."
