President Donald Trump denies giving Turkey the ‘green light’ to invade Syria in a meeting with the Italian President Sergio Mattarella on Wednesday.

President Trump said the actions of President Erdogan did not surprise him as, “he’s wanted to do that for a long time” and has been building up troops along the border.

"It’s not between Turkey and the United States, like a lot of stupid people would like us to — would like you to believe,” Mr Trump said. 

Trump insists the fight is over land that has nothing to do with the USA.
