MOSCOW, March 25. /TASS/. Sixteen patients who were hurt in the terror attack on Moscow’s Crocus City Hall concert venue have been released from hospitals over the past day, Deputy Mayor of Moscow Anastasia Rakova said.

"Moscow doctors are tirelessly working to heal patients round-the-clock. We are seeing positive progress in patients in serious and critical condition. During the past day, sixteen patients were released from hospitals," she said.

According to Moscow’s Public Health Department, seventy-six patients, including four children, are currently receiving treatment at the city’s hospitals. Six of them are in critical and 23 - in serious condition.

On the evening of March 22, a terrorist attack targeted the Crocus City Hall music venue in Krasnogorsk, Moscow Region, just over the Moscow city limits. According to the Russian Investigative Committee, the current death toll is 137, but may rise. The Moscow Region Health Ministry said that 182 people were injured.

Eleven individuals suspected of being involved in the terrorist attack have been apprehended, including four gunmen who were detained in the Bryansk Region, southwest of Moscow, as they attempted to seek refuge by crossing the nearby Ukrainian border.

President Vladimir Putin said in a televised address that, according to preliminary information, the Ukrainian side had prepared "a window" in the border especially for the terrorists to cross undetected. He promised to identify and punish all those who were behind the attack on Crocus City Hall and declared March 24 a day of national mourning for the victims.
