A family of Armenian deportees is seen in this undated handout photo taken by Armin Wegner, a German 2nd Lieutenant stationed in the Ottoman Empire. Wegner was investigating reports of Armenian massacres by taking photographs of deportation camps, primarily in the Syrian desert. A U.S. congressional panel voted on March 4, 2010 to label as "genocide" the World War One-era massacre of Armenians by Turkish forces, prompting Turkey to recall its ambassador from Washington. Turkey accepts that many Armenians were killed by Ottoman forces but denies that up to 1.5 million died and that it amounted to genocide -- a term employed by many Western historians and some foreign parliaments.
