Russia Accuses Ukraine Of Direct Involvement In Deadly Concert Hall Attack

Islamic State claimed responsibility for the concert hall massacre in March and Ukraine has repeatedly denied it had anything to do with the attack.

Ukrainian military intelligence was directly involved in a deadly attack on a concert hall near Moscow in which over 140 people were killed, the head of Russia's Federal Security Service (FSB) Alexander Bortnikov said, TASS reported on Friday.

Russia has made such allegations before. Bortnikov did not provide evidence to underpin his assertion.

"The investigation is ongoing, but it is already safe to say that Ukrainian military intelligence is directly involved in this attack," the state news agency quoted Bortnikov as saying.
