Hundreds of people stormed into the main airport in Russia’s Dagestan region and onto the landing field Sunday, chanting antisemitic slogans and seeking passengers arriving on a flight from Tel Aviv, Israel, Russian news agencies and social media reported.

Russian news reports said the crowd surrounded the airliner, which belonged to Russian carrier Red Wings.

Authorities closed the airport in Makhachkala, the capital of the predominantly Muslim region, and police converged on the facility. Dagestan’s Ministry of Health said more than 20 people were injured, with two in critical condition. It said the injured included police officers and civilians.
