Some estimates put the death toll as high as 50
A suicide bomber has killed at least 35 soldiers and wounded dozens at an army base in southern Yemen, officials say.
The attack happened while soldiers had gathered to receive their salaries at a barracks in the city of Aden, which is controlled by pro-government forces.
Some estimates put the death toll as high as 50, with as many as 70 injured.
No-one has yet said they carried out the attack, but the city has previously been targeted by jihadist groups in the region.
In August, a suicide attack claimed by IS killed at least 60 people in the city.
Yemen has been in constant conflict since March 2015, as forces allied to the exiled President, Abdrabbuh Mansour Hadi, clash with the Houthi rebel movement.
