A Polish news agency is reporting that the country plans to build six watchtowers along its border with Kaliningrad, a move that comes after Moscow said it will place state-of-the-art Iskander missiles in the Russia exclave.

The Polish news agency PAP on Monday cited a spokeswoman for border guards, Miroslawa Aleksandrowicz, as saying that six such towers would be built along the 200-kilometer (125-mile) border between Poland and Kaliningrad.

The move comes amid heightened tensions between Russia and the West over the Ukraine conflict.

Aleksandrowicz said that the cost of constructing the towers in Poland, which is on the European Union's eastern flank, would be at least 14 million zlotys ($3.8 million). Most of that is to come from EU funds.
