At least 20 people were killed on Wednesday and dozens others were injured as a suicide bomber himself up at the entrance of a police academy in the Yemeni capital, Sanaa.

"The suicide bomber blew himself up at the police academy in Sanaa and killed at least 20 people and wounded dozens," a security official told AFP news agency, on condition of anonymity.

He added that most of the casualties were police cadets who were leaving the academy for the weekend.
There was no immediate claim of responsibility for the attack.

Wednesday's blast is the second deadliest in the capital since President Abdrabuh Mansur Hadi took power in February.
The police academy is located near Sabeen Square where on May 21, a Yemeni soldier, packing powerful explosives under his uniform, blew himself up in the middle of an army battalion.

Al-Qaeda claimed it was behind that attack that killed more than 100 troops and wounded more than 300 others.
