German Chancellor Angela Merkel said on Wednesday she regretted that the U.N. Security Council was unable to agree joint language on the escalating conflict in Syria.

Speaking to reporters after a two-day cabinet meeting, Merkel added that she did not want to speculate on what may happen next in the region.

Russia has warned that any U.S. missiles fired at Syria over an alleged chemical weapons attack on a rebel enclave would be shot down and the launch sites targeted, raising the possibility of a U.S.-Russian confrontation.

Russian and US-sponsored resolutions on the alleged chemical attack in Syria, have been rejected at the UN Security Council.

U.S.-backed draft resolution called for establishing an independent investigative mechanism to conduct on-site inspections to find out who used chemical weapons.12 members of the 15-member council voted for the resolution on Tuesday, but Russia vetoed it.

An alleged chemical weapons attack hit the town of Douma in Eastern Ghouta region in the suburban area near Damascus late on Saturday, reportedly killing at least 60 people and wounding more than 1,000 others.

The Western countries blamed the incident on the Syrian government. Damascus rejected the accusations as “chemical fabrications,” which were made by the terrorists themselves in a bid to halt pro-government forces’ advances.

Damascus said the so-called Jaish al-Islam Takfiri terrorist group, which has dominant presence in Douma, was repeating the accusations “in order to accuse the Syrian Arab army, in a blatant attempt to hinder the Army’s advance.”
