From CBS News:
Russian President Vladimir Putin's government says investigators found traces of explosives amid the wreckage of the Metrojet airliner that crashed down onto Egypt's Sinai Peninsula in pieces at the end of October, proving it was a "terrorist act."Of course to President Obama, a terrorist attack is nothing but "a setback."
U.S. and other Western officials have maintained for weeks that it was likely a bomb that blew the Russian plane apart about 25 minutes after it took off from the Egyptian resort town of Sharm el-Sheikh on Oct. 31.
"According to our experts, a homemade explosive device equivalent to 1 kilogram (about 1.6 pounds) of TNT went off onboard, which caused the plane to break up in the air, which explains why the fuselage was scattered over such a large territory. I can certainly say that this was a terrorist act," the head of Russia's Federal Security Service told the emergency meeting of the Russian Security Council.
