(Reuters) - Ukraine's foreign ministry summoned Slovakia's ambassador in Kyiv on Thursday to reject accusations that it is meddling in its neighbour's internal affairs and to accuse Slovak Prime Minister Robert Fico of being a "mouthpiece" for Russia.

Here are the key developments on the 1,072nd day of Russia’s full-scale invasion of Ukraine.

The Ministry of Foreign Affairs confirmed the detention in Slovakia of a Ukrainian national on charges of "threatening national security". The Embassy of Ukraine is investigating the circumstances of the arrest as consuls are providing support.

Slovakia and Ukraine are embroiled in a diplomatic dispute following Slovakia's protest against Ukrainian remarks. The row intensified after Slovakia accused Ukraine of propaganda and Ukraine ceased Russian gas transit to Slovakia.

Ukraine is ready to consider the possibility of cooperating with European operators on gas transit to the EU, but it is the European Commission that must decide whether the European side needs such transit and whether it is ready to provide it.

Relations between Robert Fico in Bratislava and Volodymyr Zelenskyy in Kyiv have become increasingly bitter over the month.

Slovakia's Prime Minister Robert Fico, who has sought the resumption of Russian gas transit through Ukraine, will discuss the issue with European Commission officials on Thursday, his office said on Tuesday.
