'It's a good start': Pauline Hanson praises Trump's immigration ban - but says it doesn't go far enough because Saudi Arabia and Afghanistan aren't on the blacklist

• One Nation leader says Saudi Arabia and Afghanistan should be on banned list
• Pauline Hanson said President Trump needed to go further with migration ban 
• Queensland senator said states with known Islamic terror links needed targeting

Pauline Hanson says Donald Trump's migration ban doesn't go far enough.

The One Nation leader has weighed into the U.S. president's executive  order banning citizens and refugees from seven predominantly Muslim nations.

'President Trump's protections against Islamic extremism are a good start but I would go further and include Afghanistan and Saudi Arabia,' she tweeted to her 19,800 followers on Monday.

Senator Hanson said President Trump also needed to target states with known links to Islamic extremism in a bid to reduce the threat of terror attacks.

'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,' she said in a statement.

Travellers from Syria, Iraq, Iran, Sudan, Libya and Somalia and Yemen are already being banned from entering the United States for 90 days.

But Afghanistan was excluded, even though it is home to Taliban militants.

The list also fails to include Saudi Arabia, an oil-rich nation which been accused of having close ties with Islamic State, which the Kingdom denies.

Fifteen of the 19 hijackers on the planes that crashed into New York's Twin Towers in September 2001 were from Saudi Arabia.

Another two came from the United Arab Emirates with Egypt and Lebanon each contributing a hijacker but none of these nations are on President Trump's blacklist, even though the terrorist attack was in his home city.

The public policy Cato Institute released analysis last year showing no American was killed on U.S. soil by citizens from the seven nations named in President Trump's order.

President Trump has been accused of excluding from his list countries with ties to his global hotel business empire.

Like President Trump, Senator Hanson last year campaigned to ban Muslim migration.

'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 radical Islamic terror,' she said.

Senator Hanson received an invitation to President Trump's inauguration last week but she declined, with her New South Wales Senate colleague Brian Burston going in her place.
