Several detained over Russia blast
Moscow - Russia's top security official says several people with information on last month's suicide bombing of Moscow's biggest airport have been detained.
The head of Russia's Federal Security Service, Alexander Bortnikov, said in televised comments on Thursday that those detained have knowledge on the accomplices and logistics of the blast.
He said "we have an idea who the organiser of the act of terrorism is".
The January 24 attack in the international arrivals hall of Domodedovo Airport killed 36 and wounded around 180 people.
Investigators have said the suicide bomber was a 20-year-old man from the volatile Caucasus region in the south, suggesting Islamist terrorist cells known to operate there planned the attack.
There has been no claim of responsibility.
