Nearly 3 million lives have been saved by HIV/AIDS treatment but scare resources are being misspent and stigma is still keeping the most vulnerable from seeking help, according to a new book by researchers commissioned by the U.N.

Prime Minister Nuri al-Maliki told U.S. diplomats in 2009 that neighboring Iran and Syria were providing weapons to insurgent groups within Iraq, a leaked document showed Thursday.
