Donald and Melania Trump visit US troops in Iraq in Christmas trip

US President Donald Trump and First Lady Melania Trump have made an unannounced Christmas visit to US troops in Iraq.

They travelled there "late on Christmas night" to thank troops for "their service, their success and their sacrifice", the White House said.

Mr Trump said the US had no plans to pull out of Iraq.

The trip came days after Defence Secretary Jim Mattis quit over divisions about strategy in the region.

The US still has some 5,000 troops in Iraq to support the government in its fight against what remains of the Islamic State (IS) group.
