Russian court charges four men with terrorism after they attacked a Moscow concert hall, killing over 100 people.
They are accused of links to the Islamic State group, but Russia also claims Ukrainian involvement, which Ukraine denies.
The attackers were severely beaten and one appeared in a wheelchair, possibly with an eye missing.
The court holds them in pre-trial detention, while IS claims responsibility for the attack. Seven others are arrested for aiding the attackers.
The US suggests IS is solely responsible, dismissing Russian claims of Ukrainian involvement.
This attack is not the first time IS targeted Russia, as it previously attacked Russian interests abroad.
