In Iraq, more than 50 people were killed in a string of suicide bomb attacks in the capital Baghdad and at checkpoints near the oilfields in the southern province of Basra on Friday. ISIS claimed responsibility for the Baghdad attacks, which killed at least 19 people. The attacks come as thousands of families continue to flee the fighting in Mosul, where the U.S. and U.S.-backed Iraqi militaries are battling to retake the city from ISIS. The United Nations says at least 435,000 people have been displaced from western Mosul so far. A new report by Human Rights Watch has accused troops allied with the U.S.-backed Iraqi military of detaining, interrogating and torturing up to 100 residents as they fled the fighting in Mosul last month.
