Russian investigators question families of Moscow attack suspects in Tajikistan

Russian investigators were in Tajikistan on Tuesday, questioning the families of four men charged with carrying out a deadly attack on a concert hall near Moscow, three Tajik security sources told Reuters.

The sources, who were not authorized to comment publicly, said Tajik security officials had brought the families to the capital Dushanbe from the towns of Vakhdat and Gissar, and from the Rudaki district.

Tajik President Emomali Rakhmon was personally overseeing the investigation on the Tajik side, the sources said.
