Senior US officials in Pentagon agree on a different policy from President Donald Trump over presence of American forces in Syria stressing that the troops should not leave the region before mission is fully accomplished.

Addressing a forum in Washington, DC, on Tuesday, US Central Command Chief General Joseph Votel said “well over 90 percent” of land once held by the Daesh (ISIL) Takfiri terrorist group in Iraq and Syria had been recaptured, particularly in the north and eastern parts of the country, but added that the military must maintain its presence there.

“There still are some areas where they are present and that we will have to continue to operate on,” Votel said.

Speaking alongside Votel, the State Department's senior envoy to the so-called anti-Daesh coalition, Brett McGurk, agreed that “ISIL is not finished.”

“We are in Syria to fight ISIL. That is our mission and our mission isn’t over, and we’re going to complete that mission,” McGurk said.

The comments were made shortly after Trump said the US would withdraw troops from Syria "very soon," and that he intended to "bring our troops back home."

“As far as Syria is concerned, our primary mission in terms of that was getting rid of ISIL. We’ve almost completed that task, and we’ll be making a decision very quickly, in coordination with others in the area, as to what we’ll do,” Trump said at a news conference with his counterparts from Estonia, Latvia and Lithuania.

“Seven trillion dollars in the Middle East over the last 17 years, we get nothing out of it … except death and destruction. It’s a horrible thing,” he added.

The US president also suggested that the country’s military would stay in Syria if other countries, such as Saudi Arabia, would pay for it. 

In a speech in the US state of Ohio last week, the US president said the American forces would be “coming out of Syria, like, very soon,” and called on other countries to “take care of it now."

The US has reportedly more than 2,000 troops stationed in eastern Syria, in addition to several thousand others in the Arab country's north.

The US and its allies have been bombarding what they call Daesh positions inside Syria since September 2014 without any authorization from the Damascus government or a UN mandate.

The strikes have on many occasions resulted in civilian casualties and failed to fulfill their declared aim of countering terrorism.

Syria has on several occasions written to the UN, complaining that the US was flagrantly violating its sovereignty. The US supports militants fighting to topple President Bashar al-Assad and has repeatedly attacked Syrian army positions.
