US forces in Syria are 'invaders': Assad

Syria's President Bashar al-Assad called US military action in Syria as "invaders" because he hadn't given permission for them to enter the country.

According to CNN, Assad added that there's been no "concrete action" from the Trump administration toward ISIS.

"Any foreign troops coming to Syria without our invitation or consultation or permission, they are invaders, whether they are American, Turkish, or any other one. The Americans lost nearly every war. They lost in Iraq, they had to withdraw at the end. Even in Somalia, let alone Vietnam in the past and Afghanistan, your neighbouring country," CNN quoted Assad as saying.

He added that anywhere U.S. sent troops, it only create a mess and remarked that US is very good in creating problems and destroying, but they are very bad in finding solutions.

In Syria, it is working with an alliance of Kurdish and Arab militias. Their current focus is to encircle and ultimately capture Raqqa - Islamic State's base of operations in Syria.

China and Russia last month blocked U.N. sanctions on Syria over accusations of chemical weapons attacks during the war.

The new 400 troops, who are also set to help rebels take back Raqqa from ISIS, won't breach any caps because the assignment will last for no more than 120 days. There are already 500 U.S. troops stationed in Syria.

Peace talks have fallen through in Geneva, giving Assad a strong edge in the conflict on the ground.

This week, the U.S.-led coalition announced that around 400 additional U.S. forces had deployed to Syria to help with the Raqqa campaign and to prevent any clash between Turkey and Washington-allied Syrian militias that Ankara sees as a threat.
