Supporters of Yemen's former President Abed Rabbo Mansour Hadi have seized radio and television buildings in the southern city of Aden after they accused security forces of working for Shiite rebels who control the capital.

Security officials say one soldier and two Hadi supporters were killed in clashes during the seizure. Hadi, a southerner, resigned in January after a prolonged power struggle with the rebels, known as Houthis, who have controlled Sanaa since September.

The rebels have since dissolved the parliament, and Hadi and his Cabinet ministers remain under rebel house arrest. The Houthis do not control all of the country and are also battling a powerful al-Qaida branch.

The officials spoke on condition of anonymity because they were not authorized to brief reporters.
