U.S., Britain and France proposed a United Nations resolution to inquire Bashar Assad regime alleged gas attack against Khan Shykhoun village in the countryside of Idlib on April 4th, a move strongly opposed by Russia. The proposed resolution calls for the Syrian regime to further cooperate with UN investigators into the attack which killed 86 people, including 30 children. The attack triggered US Tomahawk airstrikes against a Syrian government airbase on Friday killing six pro-Assad troops. Under the proposed draft resolution, Assad regime would reveal flight plans for the day of the alleged massacre, the names of all helicopter squadron commanders and provide access to air bases where investigators believe attacks using chemicals may have been launched. President Assad denies responsibility for the attack on the opposition forces-held region. The resolution is expected to be vetoed by Russia, Assad's military ally. Last week, the UN Security Council (UNSC) failed to issue a resolution to condemn the Khan Shykhoun attack after Moscow also vetoed it. In an urgent UNSC meeting over Syria on Friday, US permanent envoy to UN, Nikki Haley accused Moscow of covering up Assad's humanitarian aggression against his people. A probe by the UN and the Organization for the Prohibition of Chemical Weapons concluded Assad regime forces carried out three chlorine gas attacks against Syrian people in 2014 and 2015. Since 2011, Syria has been into civil war that killed and wounded thousands and forced millions to flee the war-torn country.
