Iraqi soldiers work at a radio station at Makhmour base, Iraq April 17, 2016. The Iraqi army has set up a radio station at its base in Makhmour broadcasting into areas south of Mosul controlled by Islamic State militants. The radio, which reaches villages halfway to the northern city, broadcasts military anthems and messages to the more than one million civilians living there. Radio operators said their aim was to weaken the militants’ morale and reassure civilians that the military has not forgotten them after nearly two years under Islamic State control.

A replica of the truck made from matchsticks by Janusz Urbanski is pictured at his flat in Ruda Slaska, Poland May 4, 2016. Janusz Urbanski has a one of a kind chessboard he never plays, a personalised guitar he does not strum and a boat he cannot sail. Why? They are all made from tens of thousands of matches. For the last 40 years, the former Polish miner and ironworker has harboured a passion to build replicas of objects, buildings and famous sites with just matchsticks and glue.
