In Iraq, at least sixty-four people were killed Tuesday in violence around the country. The dead include four US troops. Their deaths come amid new figures showing the number of US troops wounded in Iraq has now passed twenty thousand. The top American military commander in the Middle East is now warning the Pentagon will maintain and may even increase the number of US troops. General John Abizaid says he expects at least 140,000 troops to stay in Iraq through the spring. There are currently 147,000 troops in Iraq — up 20,000 since June.
