Lithuania will spend €1.1 billion to fortify its border with Russia and Belarus, including to purchase anti-tank mines, the NATO member on the alliance's eastern flank has said.

Axar.az reports, citing RTE, Lithuania and its fellow Baltic states Latvia and Estonia - all bordering Russia - fear they could be next in Russia's crosshairs were it to win its war against Ukraine.

All three countries have been ramping up their defences since Russia's invasion of Ukraine in 2022 and boosting their border security measures over what they allege was a Russia-inspired influx of migrants at the border.

The latest spending push would allow Lithuania to "block and slow down the actions of hostile states", the defence ministry said.

In January, Lithuania announced plans to spend an annual 5-6% of its GDP on defence from 2026 to 2030.

The ministry said "intensive" work was now ongoing to identify how to "ensure the integrity of the Baltic defensive line".

It said €800m of the overall sum would be spent on anti-tank mines.
