Home Secretary Theresa May said she had been briefed by the director general of SecurityService MI5, Andrew Parker, and Metropolitan Police Commissioner Bernard Hogan-Howe on the "sickening and barbaric" attack.
Baroness Manningham-Buller, who was director-general of the securityservice MI5 between 2002 and 2007, stated that she "would like to say more" on the recent allegations.
The government accused Mr. Ayombekov, a Gorno-Badakhshan native, of assassinating days earlier a general commanding the provincial branch of the Tajik state securityservice.
