At least 12 people were killed in clashes between government troops and a renegade army unit in Sanaa on 23 October.
The unit is led by Ali Mohsen al-Ahmar, a general who broke ranks with President Ali Abdullah Saleh after protesters began demonstrating in February.
Two days earlier, the UN Security Council urged Saleh to step down immediately in exchange for immunity from prosecution. Saleh had promised to hand over power when he returned from Saudi Arabia after recovering from injuries in September.
On 26 October, thousands of Yemeni women burnt their veils in Sanaa in protest against Saleh’s brutal crackdown on anti-government demonstrations and his treatment of women. They gathered their veils into a pile and set it on fire in an act that is highly symbolic in the conservative Islamic country.
