This photo, taken January 21, depicts the destroyed airport in Donetsk in eastern Ukraine. Battles for control over the airport on the northern edge of the main separatist stronghold of Donetsk intensified over the week with rebels taking control over the terminal, although fighting is continuing in nearby settlements. The airport, which was a major showcase of the Euro 2012 Championship hosted by Ukraine, has been reduced to a hulking wreck by months of intense fighting.
