Many Iraqi migrants have said they have no intention of returning to Iraq, and some have suggested that if they cannot find a way into the European Union, they might try to apply for asylum in Belarus — creating a possibly charged situation for the nation’s autocratic leader, Aleksandr G. Lukashenko.
Unlike in past migrant crises, the vast majority of these travelers have arrived in Belarus by plane, but the major air routes they used to reach Minsk from the Middle East have been narrowing for days, slowing the flow of migrants into the country.
On Wednesday, Lebanon’s civil aviation authority instructed airlines to allow only Belarusian citizens and travelers with visas or residency permits for Belarus to board flights to the country. Last week, travel agents and thwarted travelers said that Iraqis, Syrians and Yemenis were no longer allowed to board flights to Minsk from Turkey, Iran or Dubai, in the United Arab Emirates.
The flight bans come after an intense diplomatic campaign by European Union members alarmed by the arrival of thousands of mostly Iraqi migrants into Belarus after it loosened its visa rules in August. Hoping for a path into the European Union, the migrants instead found themselves in freezing forest camps on the borders with Latvia, Lithuania and Poland.
Belarus has denied fueling the crisis, and on Thursday, the Belarusian state airline, Belavia, said it had stopped allowing citizens from Afghanistan, Iraq, Lebanon, Libya, Syria and Yemen to board flights from Uzbekistan’s capital, Tashkent, according to the state-run Belta news agency.
