US Vice President Mike Pence has raised the possibility of deploying Patriot anti-missile defense system in Estonia.
"We spoke about it today, but we didn't talk about a date or time," Estonia’s Prime Minister Juri Ratas said after Pence began a visit to the small Baltic nation on the border with Russia.
"We talked about the upcoming (Russian military) manoeuvres near the Estonian border...and how Estonia, the United States and NATO should monitor them and exchange information," Ratas was quoted as saying by RadioFreeEurope RadioLiberty reported Sunday.
Pence was in Estonia as part of a four-day tour to Estonia, Georgia and Montenegro. He was due to meet with the leaders of the Baltics - Estonia, Latvia and Lithuania - on Monday.
Later Monday, Pence is due in Georgia, a non-NATO member which has shared concerns about Russia, and also then with Montenegro that has recently become NATO's 29th member on June 5.
The US Patriot defense system is a mobile, ground-based system designed to intercept missiles and warplanes.
