A powerful suicide bomb in the Yemeni capital on Thursday killed at least 43 people in an attack on supporters of Shiite insurgents who have overrun the city, medics said.
Dozens more were wounded in the blast which struck Sanaa's Al-Tahrir square as supporters of the rebels were preparing to stage a protest, medics and rebel sources said.
Medics at nearby Police Hospital sent urgent calls for doctors to help cope with a high number of casualties.
