Authorities in Russia have arrested 11 persons including four assailants over their involvement in Friday’s deadly attack on a concert hall.
The head of the FSB security service informed Russian President Vladimir Putin “about the detention of 11 people, including all four terrorists directly involved in carrying out the attack,” Russian state news agencies cited the Kremlin as saying in a statement.
The attack left at least 115 people killed and about 145 others wounded.
Russian security agency said the assailants had contacts in Ukraine and were heading to the border.
“After committing the terrorist attack, the criminals intended to cross the Russian-Ukrainian border, and had appropriate contacts on the Ukrainian side,” the FSB said.
