Syria says it has invited the international chemical weapons watchdog to send a fact-finding mission into the country to investigate a suspected poison gas attack near Damascus over the weekend.
The Foreign Ministry says Syria will help the Organization for the Prohibition of Chemical Weapons to investigate the alleged attack, which opposition activists say killed 40 people over the weekend.
The Syrian government denies it carried out a poison gas attack in Douma, the last rebel-held town in the eastern Ghouta suburbs.
Washington has threatened to take military action against Syria to punish it for the alleged attack.
Syria calls on the OPCW on Tuesday to work with “full transparency and rely on credible and tangible evidence.”
