(QHA) -

Four Danish fighter jets have arrived in Estonia, the first time NATO warplanes will be stationed in the Baltic nation, AFP reports.

The deployment comes at a time when NATO is boosting its presence in eastern members of the alliance to allay concerns over what Western officials describe as Russia's interference in Ukraine.

At a ceremony, Estonian Prime Minister Taavi Roivas praised NATO's decision to deploy planes to the country, saying it will boost regional security. 

Until now, NATO's sole Baltic air base was in Siauliai, in northern Lithuania, from where alliance planes have carried out Baltic air patrols since 2004. 

Some 150 US troops also arrived in Estonia on Monday, part of a 600-strong force that Washington sent to Poland and the Baltics to reassure the region. Britain also sent four Typhoon fighters to Lithuania this week, while Poland contributed four MiG 29s, and France sent four Rafale jets to Poland.
