"This has coincided with a request from the Syrian Arab Republic and the Russian Federation to investigate the allegations of chemical weapons use in Douma".
In Moscow, a senior Russian lawmaker said his country is willing to help arrange a visit this week for experts from the worldwide chemical weapons watchdog to the site of a suspected poison gas attack in Syria.

Bolivia also opposed it while China abstained.
The votes on Tuesday came amid an escalating war of words between Washington and Moscow and a looming threat of Western military action following a suspected gas attack on the Syrian rebel-held town of Douma on Saturday.More news: Algerian military plane crashes with over 100 on board, reports say

Russian Federation and the United States are continuing their saber-rattling over the latest allegations of a chemical attack in Syria.
Both Trump and his defense secretary Jim Mattis abruptly canceled upcoming travel plans, as the USS Donald Cook - a guided-missile destroyer - moved to within striking range of Syria.
