At least four children were killed and 12 others injured in a fire that broke out in a summer camp in southeastern Russia, officials said Tuesday.
The fire started in a children's summer camp in Khabarovsk city on Monday evening, according to the Emergency Situations Ministry.
The fire gutted 20 out of 26 tents where 129 children aged 11-13 were staying, the ministry added.
Russian Prime Minister Dmitry Medvedev on Tuesday called a meeting with his deputies to discuss the incident.
"Obviously, there were gross security violations there. It is necessary to find out who authorized the organization of such a holiday destination," he said.
He also ordered a survey of similar camps in Russia.
The Russian Investigative Committee has begun a probe into the incident, with preliminary data suggesting the use of a heater initiated the fire.
