Russia states suspects in Crocus concert hall attack held as death toll arises to 137

Russian President Vladimir Putin has guaranteed to discipline those involved a deadly incident on a Moscow concert hall that has taken 137 lives, after authorities revealed the four main accused were caught near the border with Ukraine.

The four men appeared in court on Sunday, all exhibiting noticeable damaging and injuries, and were charged with committing a terrorist act. All four are from the former Soviet republic of Tajikistan and have been in Russia on either temporary or expired visas.

Friday’s attack on the Crocus City Hall was the deadliest terror attack on Russia’s capital in years and arises less than a week after Putin held victory in a stage-managed election, tightening his control on the country he has governed since the turn of the century.

The terror group ISIS took responsibility for the deadly attack. A US authority announced on Friday that Washington had no reason to disbelief ISIS’ declaration.

The development persuaded UN Secretary-General Antonio Guterres on Saturday to call for worldwide collaboration against ISIS.

“ISIS is a terrorist organization that is operating in several parts of the world, and it is a very serious threat to us all … and we encourage all countries to work with each other in order to make sure that ISIS will not have the capacity to strike again anywhere else in the world,” Guterres announced at a news conference.
