(CNN) -- Western intelligence missed a chance to capture or kill the suspected terrorist thought to be behind the Nairobi mall massacre, according to a former informant for both the CIA and the Danish intelligence service.
Morten Storm, who worked as an informant for five years, had forged a close relationship with the man -- a Kenyan called Ikrima -- who has been responsible for planning attacks inside Kenya for Al-Shabaab.
Storm, a Danish national, told CNN that in March 2012 the Danish intelligence agency PET had offered him one million Danish krone ($200,000) on behalf of the CIA if he could lead them to Ikrima, the target of an unsuccessful operation by US Navy SEALs last month. The SEALs raided an Al-Shabaab compound at Barawe on the Somali coast, but Ikrima escaped.
Storm's told CNN it is possible he might have got wind of the plans had he still been working for Western intelligence. But his relationship with PET and the CIA ended in mid-2012 amid disagreement about a different mission in Yemen.
"I get really frustrated to know that Ikrima had been maybe involved in the Westgate terrorist attack. It frustrates me a lot because it could have been stopped and I'm sad I can't be involved in this.
