At least 41 people have been killed in overnight clashes in the Yemeni capital of Sana’a. Witnesses say government forces fired on the headquarters of a brigade linked to the opposition against President Ali Abdullah Saleh. The Yemeni government has also cut electricity and water supplies in Sana’a’s Hassaba neighborhood, home to an influential anti-Saleh tribal leader. Another 12 people were killed in the southern city of Taiz after Saleh’s forces attacked a protest camp in the city center.
