Iraqi men who volunteered to join the fight against a major offensive by jihadists in northern Iraq stand on army trucks as they leave a recruiting center in the capital Baghdad on June 13, 2014. Iraqi forces clashed with militants advancing on the city of Baquba, just 60 kilometres (40 miles) north of Baghdad, as an offensive spearheaded by jihadists drew closer to the capital.
