FNA- Iranian Ambassador and Permanent Representative to the United Nations Gholamali Khoshrou blasted as an irrational move the US President Donald Trump's travel ban against Iran, Libya, Syria, Somalia, Sudan and Yemen instead of Saudi Arabia.

"No travel ban can prevent repetition of terrorist operations because its culprits are inside the US. On the other hand, 15 of the 19 people who carried out the September 11, 2011 terrorist operations were Saudi nationals. The same country whose leaders stood in a sword dance with Trump to celebrate the arms deal worth hundreds of billion dollars," Khoshrou said on Sunday.

He stressed that the travel ban against the six Muslim states is not aimed at guaranteeing the US security and is rooted in Washington's Islamophobia and racist policies.

People from six mainly Muslim countries and all refugees now face tougher US entry due to Trump's controversial travel ban.

It means people without "close" family or business relationships in the US could be denied visas and barred entry.

Lawyers took up positions at US airports, offering free advice.

The executive order does not affect people who already have valid visas or green cards.
