Israel is lobbying the United States to keep Syria weak and decentralised, including by letting Russia keep its military bases there to counter Turkey's growing influence in the country, four sources familiar with the efforts said.

To contain Turkey, Israeli officials have sought to persuade US officials that Russia should keep its Mediterranean naval base in Syria's Tartus province and its Hmeimim air base in Latakia province, the sources said.

The source added that such an allegation is a lie made up by Israel "to cover up its plans regarding Syria after the fall of the Assad regime."
