Russian President Vladimir Putin called a meeting of security and law enforcement officials Monday, the day after a mob stormed the airport in the southern region of Dagestan after a flight from Israel landed there.

Hundreds of angry men, some carrying banners with antisemitic slogans, rushed onto the tarmac of the airport in Makhachkala, the capital of the predominantly Muslim region, on Sunday night, looking for Israeli passengers on the flight from Tel Aviv, according to Russian news reports.

More than 20 people were injured, with two in critical condition, Dagestan’s Health Ministry said. The injured included police officers and civilians, it said.

At least 60 people were detained in the unrest, the local Interior Ministry said. It was not clear if charges were filed against any of them, but Russia’s Investigative Committee said it opened a criminal probe on charges of organizing mass unrest.
