The security authorities have been placed on high alert in Yemen's capital after the interior ministry got information an Al-Qaida bomber was reported to have entered Sanaa to carry out attacks.
The ministry said it had obtained information that Abdullah Muhammad Jabir Al-Shabwani had infiltrated into the capital for a car bomb attack.
The suspect has a Land Cruiser car 2009, it said, pointing out that the security authorities have been placed on high alert and ordered to take necessary measures including precise checking at exits and entries to face sabotage and terrorist attacks.
Meantime, the army is continuing an offensive on Al-Qaida militants in southern and southeastern regions including Abyan, where the militants seized some key towns last year.
On Monday, at least 22 militants were killed when the forces advanced in Zinjibar, the capital, and other towns clear militants from them.
The expanded operations started on Saturday after fierce battles with the militants in the past weeks in which hundreds of militants were killed and injured.

The US helps in the war on militancy in the country and drone attacks have killed many terrorists including senior Al-Qaida leaders.
