Yemen has identified the suicide bomber who attacked the convoy on British ambassador in Sana'a as a high school student.
Othman Ali Noman Al-Celwi, 22, was reported to have been trained by Al-Qaeda in Marib before he detonated himself on Monday morning at the Berlin Park in Sana'a.
The ambassador and other British diplomats were unhurt.
Three passers-by got minor injuries in the attack.
Several suspects have been arrested in the Secretariat Capital in connection with the suicide bomb that came amid an intensified campaign against Al-Qaeda in the country.
The authorities said the attack was a desperate attempt by terrorists after several successful terror operations in late last year and in early this year in which scores of operatives were killed, injured and arrested.
