"In taking account the current uncertainty around the world, we are applying the toughest security measures our country has ever seen – even tougher than during the visit by President George W. Bush in 2006," Pevkur said in an interview with Eesti Päevaleht.

The minister is confident that Estonia will handle this challenge very well; a statement confirmed by Kristian Jaani, the Estonian police chief in charge of Tallinn.

"Over the years, Estonia has hosted the visits and looked after the foreign secretaries of NATO, German Chancellors, Her Majesty the Queen Elizabeth II, as well as the US President in 2006. We have always managed the security challenge well," Jaani said.

The security operation

• 1,700 police and border guard officers on duty before and during the visit on 3 September
