Polish Defence Minister Mariusz Blaszczak said the missiles will be deployed near the Ukrainian border, securing an agreement less than a week after an explosion killed two people in a village near the Ukrainian border.

The incident came nine months after President Vladimir Putin launched the invasion of Ukraine. It was defused after Nato and Polish authorities attributed the blast, which occurred during a broad Russian missile strike on Ukraine, to Ukrainian air-defence targeting a Russian projectile.

“Poland is our friend, ally, and stands out as a neighbour of Ukraine,” German Defence Minister Christine Lambrecht said in a statement on Monday. The details of the agreement will be worked out by the technical staff, she added.

The deal stands in contrast to the fraught relations between the two countries. Poland’s governing party has pilloried the government in Berlin for what it calls a slow response to Russian aggression. Warsaw this year launched a campaign to demand Germany pay $1.3-trillion in compensation for wartime damages.

The blast opened a debate about air-defence systems in Ukraine as well as in the Nato member states in the region. In September, Poland began receiving equipment for its first two US Patriot battery systems, which are set to become operational in late 2023.

The Raytheon-made surface-to-air Patriots can shoot down attacking missiles but also have hi-tech sensors that help in identifying what’s in the air.

Lambrecht announced the offer in an interview with the Rheinische Post newspaper on Monday. She said Germany intends to extend a deployment of Patriot batteries in Slovakia, a Nato member state that also borders Ukraine, through 2023 – “and maybe even longer”. Nato must also look for ways to strengthen air defences in the Baltic region, she told the newspaper.
