"Fifty-four individuals have been apprehended on suspicion of involvement in the terrorist acts. Forty-five people have been charged and they are now under arrest, including fifteen women. The involvement of the remaining nine individuals detained is being investigated," Kadyrov said. "Some of the detained individuals have testified that they were trained in terrorist camps by Arab instructors who had previously trained Al-Qaeda militants."
Kadyrov said 412 people have been brought in for questioning and investigators have seized a large amount of weapons from some of those charged in the attacks.
Uzbek officials say that at least 47 people died, including 33 alleged radicals and 10 policemen, in four days of attacks that began on 28 March.
