One Nation leader Pauline Hanson has said that President Trump's controversial migration ban hasn't gone far enough.

According to Hanson, more countries should be included in the ban which has blocked immigrants and refugees from seven predominantly Muslim nations from entering America.

"President Trump's protections against Islamic Extremism are a good start, but I would go further and include Afghanistan and Saudi Arabia," Hanson said in a tweet.

Hanson expanded on her remarks in a statement, which praised Trump's executive order.

"The people of America have elected Donald Trump because they wanted to regain control of their borders and protect themselves against the influence and threat of Radical Islamic terrorism,"

"Our politicians can no longer sit by and ignore the fact that unless we do something, like ban Islamic immigration, Australia will continue to face an ever increasing threat from Islamic terror.”

Trump's order has banned citizens from Iran, Iraq, Somalia, Sudan, Syria and Yemen from entering the country.

The move has sparked demonstrations around the world, with thousands of people in the UK protesting the order.

Demonstrations have also taken place in airports around America, in front of Trump Tower in New York and outside the Whitehouse.
