Estonia and Latvia have agreed to jointly purchase a mid-range air defence system, the Estonian defence ministry said in a statement on Thursday.
"Russia's aggression in Ukraine clearly demonstrates the need for air defence systems," Latvian Defence Minister Artis Pabriks was quoted in the statement as saying.
The purchase will be managed by Estonia on the advice of the defence chiefs of the two Baltic states, under a letter of intent signed by the defence ministers during the NATO summit in Madrid, the statement said.
