In Yemen, former President Ali Abdullah Saleh was confirmed dead Monday, after a video posted online by Houthi rebels showed Saleh’s lifeless body dumped in the back of a pickup truck. Saleh was killed as pitched battles continued to rage in the capital, Sana’a, between Houthis and forces allied with Saleh’s political movement. The killing could escalate Yemen’s civil war, which has brought 7 million people to the brink of famine and fanned a massive cholera epidemic.
