The prospect of a USA strike on Syria in retaliation for an alleged chemical attack, coupled with a missile raid apparently carried out by Israel that killed Iranian military personnel, has underscored the risk that the conflict is on the brink of a unsafe escalation. While many observers initially believed the U.S. had carried out the strike in response to the Assad regime's alleged chemical attack on civilians in the Damascus suburb of Douma, Russia, Syria and Iran publicly blamed Israel.
Iranian and Pakistani aid groups are sending humanitarian relief supplies to recently liberated Syrian towns in Eastern Ghouta, Press TV reports.
The Syrian government has had a good cooperation with the United Nations on chemical matters, Qassemi said, adding that the global community, after Syria's accession to the Chemical Weapons Convention, destroyed all the chemical weapons production and manufacturing facilities of the Arab country.
An alleged chemical attack that left dozens dead in Syrias rebel-held town of Douma has sparked worldwide outrage, with US President Donald Trump warning there would be a "big price to pay". Iran has blamed Israel for carrying out the attack on Tyias or T4, near Homs.
The Jewish state has carried out attacks in Syria, alleging that its longtime enemy Iran is building military bases there. Velayati, upon his arrival in Syria on Tuesday, said the strike would "not remain without response", Iranian media reported.
"President Putin, Russia and Iran are responsible for backing Animal Assad.
When the Syrian regime continues to use chemical weapons against civilians with impunity, protected by Russian Federation and Iran, that line has always been crossed".
"By striking [Syrian President Bashar al-Assad] and his Iranian allies just a day after Trump warned them of the price they would pay".
Syria has been accused multiple times of using toxic weapons including sarin gas in the country's seven-year war, which has killed more than 350,000 people.
The Syrian conflict began when the Baath regime, in power since 1963 and led by Assad, responded with military force to peaceful protests demanding democratic reforms during the Arab Spring wave of uprisings, triggering an armed rebellion fuelled by mass defections from the Syrian army. It has investigated more than 70 cases of alleged toxic gas attacks in Syria since 2014.
