The United States made it clear to Russia and Turkey that they do not like what is happening in Idlib, Robert O'Brien, White House national security adviser, said on Wednesday.

According to him, there is a very bad situation in Idlib and they have told Russia and Turkey that the US did not like it, RIA Novosti reported.

The US is not ready to solve the problem with its troops that they did not create, he added.

Turkish President Tayyip Erdogan said earlier he had called on his Russian counterpart Vladimir Putin to put pressure on Syrian President Bashar al-Assad to stop the offensive in the Idlib province and withdraw from Turkish observation posts by the end of February, otherwise threatening with a military response.

Four de-escalation zones have been created in Syria according to the deal reached in May 2017 at the talks in Astana by representatives of Russia, Iran and Turkey. The territory of three of them in 2018 came under the control of Damascus. The fourth zone is still not subject to the government of the republic. Moreover, most of it was captured by terrorists from Al-Nusra Front. Russia and Turkey agreed in Sochi in September 2018 on the creation of a demilitarized zone in Idlib, where there are more than a dozen different units.
