MOSCOW - Five people were killed and dozens of others injured as a Russian plane made an emergency landing on a river in Siberia on Monday.

Two passengers were still unaccounted for.

Russian Emergencies Situation Minister Sergei Shoigu said 33 passengers, including one child, and four crew members were aboard the An-24 aircraft.

Itar-Tass news agency said the plane landed on the western Siberia's Ob River at around 9 a.m. Moscow time (0500 GMT) after a fire was found in one of the engines, adding that the plane partially disintegrated during the landing.

Yaroslava Karpenko, an official of the regional civil defense department, told Interfax news agency that 30 people were injured in landing and that four of them were in grave condition.

The plane, en route from Tomsk to Surgut, belongs to Angara airline.

After the accident, Russian President Dmitry Medvedev hosted a meeting with Shoigu and ordered to ground all An-24 aircraft over safety concerns.

"Everything I said about Tupolev-134 planes must be applied equally to An-24s," Medvedev was quoted by local media as saying.

The An-24 type aircraft has been involved in a series of fatal accidents over the past few years.
