Tension surface over Smolensk crash

Poland runs into “the Russian obstacle”, reports Gazeta Wyborcza. Quoting Polish PM Donald Tusk, the Warsaw daily explains that, “The Russians are not handing over to the Poles documents necessary for explaining the Smolensk crash,” that killed 96 persons on 10 April, including President Lech Kaczyński. Polish prosecutors have still not received answers to important questions about air traffic control operations, Smolensk airport equipment, or Russian aviation procedures. The Interstate Aviation Committee that coordinates the investigation on the Russian side has "from the outset remained silent on factors that might suggest Russian co-responsibility," notes the Warsaw-based daily.
