In a latest development in the Delhi Red Fort blast case, police sources have revealed that the arrested terrorist and Dr Umar Mohammad was in contact with a handler identified as ‘UKasa’. Investigating agencies suspect that ‘UKasa’ might be a code name used by the handler to conceal their identity. According to intelligence inputs, the handler’s location has been traced to Ankara — the capital of Turkey. Agencies are also probing reports that several individuals from India had travelled to Ankara in March 2022, during which they may have been radicalised or brainwashed.
