London suicide bombers "young, emotional and ignorant."

CNN-AP: An Egyptian chemist freed after three weeks in custody for questioning about deadly bombings in London said he casually knew two of the attackers. He called one of them "very kind and very nice."

After his release Tuesday, the clean-shaven Magdy el-Nashar told reporters outside his home that he had nothing to do with the July 7 mass-transit attacks, which killed 52 people and the four bombers.

..The 33-year-old chemist said he met one of the bombers, Jamaican-born Jermaine Lindsay, in Leeds during the last month of the Muslim period of fasting, Ramadan, which was in October and November.

El-Nashar said that in June, Lindsay asked for help finding a place to live in Leeds, saying he wanted to move there from London with his wife and child.

He said he located quarters for Lindsay through his landlord and was then introduced by Lindsay to a man called Mohammed, who turned out to be Hasib Hussain, another of the July 7 bombers.

El-Nashar said Islam was not an issue in the attacks, and he called the suicide bombers "young, emotional and ignorant."

"Their knowledge of Islam was very superficial," he said. "They have seen oppression in Iraq, Palestine, Afghanistan and Bosnia."

..El-Nashar then issued an appeal for world governments to "stop oppressing people, killing and bombing people so that ignorant and emotional people don't have an excuse for such activities." Read more
