Questions remain over the extremist links of Lee Rigby's killers. Michael Adebolajo is thought to have flown to Kenya to train and fight with al-Qaeda in Somalia. The man who mentored Michael Adebowale says he believes he was radicalised when in jail
In 2010, Michael Adebolajo visited Kenya and is believed to have been preparing to train and fight with al-Qaeda-linked militants in Somalia.
According to intelligence files seen by ITV News, he travelled to the country's coast and met a group under the surveillance of anti-terrorism police.
It is claimed they contacted a radical cleric for help to get to Somalia. That cleric told ITV News correspondent Rohit Kachroo: "Michael was a very nice young man - a man of strong character and if you look at him you believed in his cause."
"They were to join their fellow Mujahideens [Muslims who proclaim themselves warriors for their faith] in Somalia and to assist, put a stop to the oppression many of the Muslims in Somalia are going through."
The brother of soldier murderer Michael Adebolajo refused to condemn the killing, suggesting the events were a result of UK foreign policy.
