Over the forced landing of a Ryanair Holdings Plc jetliner and the arrest of a dissident journalist, the US presidential administration has said it will be re-imposing sanctions over nine Belarusian state-owned enterprises and is developing new sanctions which will target Belarusian President Alexander Lukashenko.

The White House Press Secretary told reporters on Friday issuing a “Do Not Travel” warning to American Citizens urging them to steer clear of Belarus. Psaki also issued a notice for American Pilots to “exercise extreme caution” when considering flying in Russian Airspace.

“Belarus’s forced diversion of a commercial Ryanair flight under false pretenses, traveling between two member states of the European Union, and the subsequent removal and arrest of Raman Pratasevich, a Belarusian journalist, are a direct affront to international norms,” Psaki said in the statement.

The Treasury Department is also crafting an executive order that will “provide the United States increased authorities to impose sanctions on elements of the Lukashenko regime, its support network, and those that support corruption, the abuse of human rights, and attacks on democracy,” Psaki said.

Belarus earlier this week forced the landing of a jetliner carrying Raman Pratasevich, a Belarusian journalist and outspoken critic of the Lukashenko regime, as it was traveling between Greece and Lithuania. Pratasevich, 26, has been detained in Minsk alongside his girlfriend, Sofia Sapega, despite international calls for their release.
