US troops cross into Iraq from Syria: witnesses

United States troops have crossed into Iraq from Syria through the Sahela border crossing in the northern province of Dohuk, Reuters witnesses said on Monday.

Reuters video images showed armoured vehicles carrying troops into Iraq, part of the U.S. withdrawal from Syria. A Reuters cameraman saw more than 100 vehicles crossing.

An Iraqi Kurdish security source also told Reuters that U.S. troops had crossed into the semi-autonomous Kurdish Region of Iraq.
