The UN Security Council will vote Wednesday on a draft resolution demanding that the Syrian government cooperate with an investigation of the suspected chemical attack last week in Idlib province, US diplomats said. The vote is scheduled for 3 p.m. (1900 GMT).

Russia is expected to use its veto to block the measure, diplomats said.
The draft resolution expresses "horror" at the reported use of chemical weapons in Khan Sheikhoun and condemns the alleged attack. It expresses full support for investigators from the Organization for the Prohibition of Chemical Weapons (OPCW) and the joint UN-OPCW investigative panel tasked with determining who is responsible for such attacks. 
The text calls on the Syrian government to provide flight plans, flight logs and other information on its military operations on April 4, hand over the names of commanders of any aircraft and provide access to all air bases to UN investigators.
