Today is a day of national mourning in Russia following the massacre at a Moscow concert hall that killed more than 130 people, the deadliest attack in Europe claimed by the Islamic State (IS) group.
Russian President Vladimir Putin has vowed to punish those behind the "barbaric terrorist attack", saying four gunmen who tried to flee to Ukraine had been arrested.
Kiev has strongly denied any link, and Ukrainian President Volodymyr Zelensky has accused Putin of trying to shift the blame to Kiev.
In his first public statements on the attack, Putin did not mention IS's statement claiming responsibility for the attack.
At least 133 people were killed in the late hours of March 22 by masked gunmen who stormed the Crocus City concert hall in the northern Moscow suburb of Krasnogorsk.
Islamic State wrote on Telegram that the attack was "carried out by four IS fighters armed with machine guns, pistols, knives and firebombs" as part of the "raging war" with "countries fighting Islam".
It is the deadliest attack in Russia in almost two decades.
Russian authorities expect the death toll to rise further, and more than 100 wounded have been hospitalized - some of them in serious condition.
Russia's Investigative Committee, which investigates serious crimes, said rescuers were still removing bodies from the burned building.
The Emergencies Ministry has so far named 29 of the victims as the fire complicates the identification process.
The ministry released a video showing heavy equipment arriving at the scene of the fire to dismantle the damaged structures and clear the debris. /BGNES
