A wall is inscribed with the names of killed Polish officers during a commemoration ceremony at a memorial complex in Katyn, about 350 km (217 miles) west of Moscow, April 10, 2013. The memorial was erected on the spot of the 1940 massacre where thousands of Polish officers were killed by the Soviet NKVD secret police.
