Yemeni forces have cracked a cell of Al-Qaeda operatives suspected of carrying out a suicide bombing in Sanaa in May that killed more than 100 troops, a security official was quoted as saying on Thursday.

“Security forces have captured (members of) the terrorist cell behind the attack on Sabeen Square,” national security chief, Ali Mohammed Al Ansi, was quoted as saying by 26 September, a daily owned and published by the ministry of defence.

He was referring to the location of the May 21 bombing in Sanaa that targeted troops rehearsing for a military parade.

Ansi gave no further details about the arrest.

On June 20, security forces had announced the arrest of Majed Al Qulaisi, a member of the Al Qaeda cell that planned the deadly suicide attack.

Ansi vowed to continue the “hunt” for Qaeda fighters, saying security forces have carried out a “series of operations against Al-Qaeda terrorists” across Yemen.

Last week, Yemeni troops took control of the southeastern town of Azzan, the last Qaeda bastion in Yemen’s troubled southern and eastern provinces where the militants had established total control.
