The UN Security Council and Secretary General Ban Ki-moon on Wednesday strongly condemned a bomb attack at a police academy in Yemen that killed 37 people.

"The 15-member council said the perpetrators of the "horrific bomb attack" should be brought to justice and urged all countries to cooperate with the Yemeni authorities to do so," he said Thursday.

The car bomb at a police academy in Sanaa exploded as dozens of Yemeni recruits were lined up to register, killing 37 people and wounding 66 others.

The attack highlighted growing instability in Yemen, which has been sliding towards chaos since an uprising in 2012 ousted longtime leader Ali Abdullah Saleh.

Ban condemned the attack "in the strongest terms" and called on "all Yemenis to work together to fight terrorism and to bring security and stability to Yemen."
