Video footage on social media appears to show people running through Makhachkala airport in the southern region of Dagestan - many waving Palestinian flags - on Sunday evening.

"Unauthorised citizens" broke on to the runway when a Red Wings flight from Tel Aviv was due to land there, Russian media said.

The identification number on the tail of plane suggested it had come from Israel, according to tracking website FlightRadar 24.

All flights from the airport, which is in a predominantly Muslim part of Russia, were diverted to others nearby, Russian aviation authority Rosaviatsia said.

Around 20 people were injured, according to local health authorities.

Russian state-owned news agency RIA said around 60 people had been arrested and the identity of 150 of what it called "the most active protesters" had been identified.

It said nine police officers had received injuries in the incident, two of whom were being treated in hospital.

Security officials said they were able to clear the group from the runway at 10.20pm local time. The airport will remain closed until "normalisation" of the situation, Russian officials said.

The office of Prime Minister Benjamin Netanyahu commented, saying Israel "expects the Russian law enforcement authorities to protect the safety of all Israeli citizens and Jews wherever they may be and to act resolutely against the rioters and against the wild incitement directed against Jews and Israelis".

The Israeli ambassador to Russia added that they would work with Russian authorities to "ensure the safety of Israelis and Jews".

Ukrainian President Volodymyr Zelenskyy, who is Jewish, posted about the incident at the airport on X, formerly known as Twitter.

He wrote: "This is not an isolated incident in Makhachkala, but rather part of Russia's widespread culture of hatred toward other nations, which is propagated by state television, pundits, and authorities."

Israel has increased its operations in Gaza in response to the 7 October Hamas incursion.

Speaking at a news conference on Sunday, Rear Admiral Daniel Hagari, spokesperson for the Israeli Defence Forces (IDF), said it "continues to gradually expand our combat operations according to the plans in order to achieve the goal of the war".

So far, more than 1,400 Israelis have been killed in the conflict, according to the Israeli military. The Gaza health ministry says over 7,700 Palestinians have been killed.
