The Czech government has backed allowing its fighter jets to protect neighbouring Slovakia's air space from September, the Defence Ministry said on Wednesday, APA reports citing Reuters.
Slovakia has sought help from its NATO allies as it looks to ground its Russian-made MiG-29 fighter jets in August under long-standing plans to modernise the military.
Slovak government officials have said the old jets could be sent to neighbouring Ukraine to help Kyiv defend itself against Russia's invasion.
From September, the Czech army's Gripen JAS-39 fighter jets will provide air policing for Slovakia until at least the end of 2023, the Czech Defence Ministry said. Poland is also expected to take part, it said.
More details will come as part of a joint declaration from the countries to be signed in the near future.
Slovakia borders Ukraine in the east and has been an entry point for refugees fleeing fighting during the five-month war. Bratislava has also backed Kyiv with weapons and other aid, and NATO is boosting its presence in Slovakia.
