Bulgaria will allow U.S. military aircraft to stay in the country only until the end of June after the United States failed to approve a visa-free system for Bulgarian visitors, Prime Minister Rumen Radev said.
"We have our priorities and procedures, and we cannot respond positively to the request for long stays of aircraft and tanks at the Sofia airport," Radev said.
Bulgaria hosts U.S. military aircraft in Sofia under an agreement valid until the end of May. The government extended the stay until the end of June to give the U.S. time to reconsider.
