US intelligence agencies are trying to put a spoke in Russia’s wheels in Syria by working to incite a Russo-Saudi clash in the region, the German newspaper Deutsche Wirtschafts Nachrichten (DWN) reported.

The situation in Syria might get worse because the US government stands behind a scheme to make Saudi Arabia provide greater support to various Syrian opposition forces amid the ongoing Russian airstrikes, the newspaper said.

The Saudi's support of Syrian rebel factions undermines the efforts of troops loyal to the government of Syrian president Bashar al-Assad, who is a Russian ally. In other words, by supporting Syrian rebels, who are fighting against al-Assad, Saudi Arabia challenges the Russian anti-ISIL campaign in Syria, DWN said.

The offensives of the Syrian army backed by Russian air strikes began to slow down because of the increased Saudi support to rebels.

"Saudi is in a state of madness, escalating to the greatest degree," a source close to the Syrian army said, as cited by Reuters.

Although Barack Obama agreed to fight ISIL together with Vladimir Putin, the US government can't officially challenge the Russian anti-terrorist campaign in Syria, but with the help of Saudi Arabia, US intelligence services are working to further de-stabilize Syria using the hands of Saudi-backed rebels, DWN said.

At the same time, Saudi Arabia is also interested in the overthrow of the current Syrian government because Assad is an Iranian ally and Saudi Kings seek to weaken the influence of Iran in the Middle East.

Syria has been in a state of civil war since 2011, with the country's government fighting a number of opposition factions and radical Islamist groups, including Islamic State and the Nusra Front.

The United States and its allies have been conducting airstrikes on ISIL positions in Syria since 2014, without approval from the UN Security Council or Damascus.

Russia has been conducting precision airstrikes against terrorist targets in Syria at the request of President Bashar Assad since September 30.
