The Metropolitan Police have identified four men suspected of carrying out last week's London bombings, UK media reported Wednesday.

Media reports suggest the four bombers were aged between 19 and 30 and were so-called "cleanskins" - with no convictions or known terror involvement.

The Times newspaper named two of the dead suspected bombers as Hasib Hussein, 19, and 22-year-old Shehzad Tanweer, both Britons of Pakistani origin who lived in Leeds.

Police say it is "very likely" that one of the four died in the blasts on London's transport network, and it is possible that all four bombers blew themselves up deliberately.

The four men had traveled to London on the day of the blasts and been captured on closed-circuit television footage at King's Cross station shortly before 8:30 a.m.

British government has already said last Thursday's attacks are likely done by Islamic extremists, blamed for the 9/11 attacks on the United States and the bombing of Madrid's train network last year.
