Officials in the Pentagon and the White House told Asharq al-Awsat newspaper that  "These airstrikes will not be disclosed and the US won’t claim them publicly".

Some analysts expressed concerns over the mounting tension between Russia and the US as this might drift the Syrian war and spur a military conflict. However, the Pentagon source seems certain that a US decisive military step can be taken without any risk or real danger.

Meanwhile French FM Jean-Marc Ayrault in joint press conference with Secretary of State John Kerry on Friday spoke about the French efforts to push towards a ceasefire in Syria, describing the situation in Aleppo as “extremely dangerous”.

Ayrault met, earlier, Russian officials to discuss efforts to reach a ceasefire especially after Washington-Moscow brokered syria truce collapsed, tension increased and accusations were being exchanged.

Yet, the political arena seems suspicious towards Obama’s administration desire or ability to take such a tough decision at the meantime.

On Thursday Russia warns US against targetting Syrian army and said Moscow was ready to use its air defense systems to protect them.

Russian Defense Ministry spokesman, Major General Igor Konashenkov, said that any missile attack or airstrike on the territories controlled by the Damascus government would pose a clear threat to Russian military personnel.
