A car bomb has exploded behind a military hospital in Yemen's capital, Sanaa. The blast caused dozens of casualties, including civilians, according to security officials.
Security officials with links to Yemen's rebels - known as Houthis - said the blast had targeted the homes of several Houthi leaders, but did not give further details on how many people were killed or wounded.
The injured were mourning victims of a previous attack, according to a medical source.
The area was cordoned off by Houthis after the explosion and people were prevented anyone from entering as ambulances rushed to the scene.
Meanwhile, fighting continued in cities across the country on Monday, with Saudi-led airstrikes on the Houthi stronghold of Saada, as well as Aden and Shabwa.
In Taiz and the port city of Aden, street fighting raged on with heavy weapons, according to security officials who have not declared allegiance to any side in the conflict.
Also on Monday, the Houthis announced they had fired a Scud missile at Saudi Arabia, in what would be the second such attack since fighting between a Saudi-led coalition and the rebels began in the spring.
The conflict in Yemen pits the Shiite Houthi rebels and allied troops loyal to former President Ali Abdullah Saleh against southern separatists, local and tribal militias, Sunni Islamic militants and loyalists of the exiled president. The rebels seized the capital in September.
