Croatian Prime Minister Andrej Plenkovic said on Monday after a meeting with President of the European Council Charles Michel that the two of them condemned the forced landing of a Ryanair civil plane in Belarus and demanded an international investigation.

Plenkovic met with Michel in Brussels ahead of an EU summit. Croatia’s Prime Minister wrote on Twitter that he had spoken with Michel about “the fight against Covid-19, the vaccination process, Croatia’s entry into the Schengen area and the euro area and the continuation of enlargement.”

“We condemn the unacceptable move by the Belarusian authorities and demand an international investigation,” Plenkovic said.

Plenkovic then spoke with the Commissioner for Home Affairs Ylva Johansson at the Commission’s headquarters.

The two-day summit of the leaders of 27 EU member states starts on Monday evening, and the agenda includes meeting the set goals for climate protection, foreign policy issues and the Covid-19 situation.

EU leaders will also address the unprecedented move by the Belarusian authorities, who on Sunday forced a Ryanair flight from Greece to Lithuania to land in Minsk and then arrested Roman Protasevich, one of the main opposition activists who was on board. It is expected that there will be a debate on measures the EU could introduce against the Belarusian regime.
