LONDON (Reuters) - Three Britons recruited as suicide bombers in an Al-Qaeda-inspired plot to blow up trans-atlantic airliners in mid-air using liquid explosives were jailed for at least 20 years on Monday. The plots ringleaders hoped to evade airport security by smuggling homemade bombs onto US-bound flights using liquid explosives disguised as soft drinks. It triggered a global clampdown on passengers carrying liquids. Ibrahim Savant, 29, Arafat Waheed Khan, 29, and Waheed Zaman, 26, all from London, had denied conspiracy to murder and said their videos were part of a documentary. Judge Timothy Holroyde said the men were foot soldiers unaware of their intended targets and took no part in planning the attacks or assembling the bombs. However, he said all three intended to kill an uncertain but potentially large number of innocent men, women and children, the Press Association reported. In furtherance of that conspiracy, each of you recorded a suicide video in which you described yourself as being blessed by the opportunity to take part in that mission, the judge told Woolwich Crown Court. The court heard how a team of suicide bombers planned to assemble and detonate the hydrogen peroxide devices in mid-air. Twelve people have been convicted in connection with the plot in a series of trials. Detectives took nearly 10,000 statements, searched 800 computers or memory sticks and visited countries including Pakistan, the United States, South Africa and Japan.
