Government of the Republic of Korea (ROK) has decided to ban all travel to Ukraine, according to Yonhap news agency citing the country's foreign ministry.

"It has been decided to urgently issue a travel warning level 4 (travel ban) for all regions of Ukraine from 0 a.m. on the 13th, Korean time," the ministry was quoted as saying. 

The ministry also asked ROK nationals staying in Ukraine to urgently evacuate to a safe third country, or return to the country, using available flights.

The decision was made due to rising military tensions in the country, according to the report.
