FACTBOX - The men in the 21/7 bomb plot trial

(Reuters) - A jury failed to reach verdicts on Tuesday against two men accused of plotting botched suicide bombings on London's transport system on July 21, 2005.

On Monday four others, Muktah Said Ibrahim, Hussein Osman, Yassin Hassan Omar and Ramzi Mohammed, were found guilty of conspiracy to murder.

However the jury could not agree on a verdict for Manfo Kwaku Asiedu and Adel Yahya who faced the same charges.

Here are some details about the convicted men:

MUKTAH SAID IBRAHIM:

Ibrahim, the plot's ringleader and self-confessed bombmaker, was born in Eritrea and came to Britain in the 1990s when he was a teenager to escape the war with Ethiopia.

He tried to set off a bomb on a bus near Bank underground station in London's financial district, although he claimed he had changed his mind and that it had gone off by mistake.

Ibrahim became a practising Muslim in 2003 and by 2004 he regularly distributed Islamic literature in central London and was arrested on Oxford Street in the heart of London's main shopping district for a public order offence.

Prosecutors said he had undergone terrorism training in Sudan in 2003 although he said he had been visiting relatives.
