A passenger jet with 62 passengers and five crew members onboard crashed near the city of Aktau in Kazakhstan on Wednesday, the country’s authorities said.

Kazakhstan’s health care minister said that at least six people onboard had survived the crash, Russian news agencies reported. Russia’s RIA state news agency reported that 25 people had been hospitalized with various injuries, five of them in grave condition.

Operated by Azerbaijan’s Azal airlines, the Embraer-190 plane was traveling from Baku, the Azerbaijani capital on the Caspian Sea, to Grozny in Russia’s Chechnya republic in the North Caucasus. Russia’s RIA state news agency reported that the plane had been rerouted to Kazakhstan because of fog in Grozny.

The airline said in a statement that its plane had made an “emergency landing” about 1.8 miles away from Aktau in Kazakhstan.

Kazakhstan’s emergency situations ministry said it had started an investigation into the crash.

Firefighters and other emergency services were dispatched to the scene, according to Kazakhstan’s emergency authorities.
