Islamabad, March 4 (RHC)-- In Pakistan, the latest attack on a polio vaccination team killed at least 13 people in the country’s northwest.

No one claimed responsibility for the attack, but the Taliban has previously targeted health workers after it was revealed the CIA used a fake vaccination program to help locate Osama bin Laden.

Hours after the attack the Pakistani Taliban announced a month-long ceasefire. Talks between the Taliban and the government had broken down last month.

In other news, Osama bin Laden’s son-in-law is on trial in the United States. Suleiman Abu Ghaith is charged with urging the killing of Americans after the September 11th attacks in 2001. He is the highest-ranking member of al-Qaeda to stand trial inside the United States following the 9/11 attacks.
