Explosive Traces Discovered In Second Downed Russian Plane

MOSCOW, Aug 28 (AFP) - Investigators have discovered traces of the explosive Hexogen in the wreckage of the second plane downed this week in Russia, ITAR-TASS news agency reported Saturday.
"An additional analytical examination of fragments of the Tu-134 plane, which crashed Tuesday in the Tula district, showed traces of Hexogen," the agency quoted a spokesman for the FSB intelligence service as saying.
The same substance had been found a day earlier in the other plane, which fell to the ground near the southern city of Rostov-on-Don at an almost identical moment, leading Russian officials to describe that attack as an act of "terrorism".
The spokesman, Sergei Ignachenko, said the FSB was looking at introducing aviation security systems used at airports in Israel which were "considered the most effective in the world", Interfax reported.
"In line with a decree from the Russian president, the FSB is studying international experience in the fight against terrorism targeting aviation transport," Ignachenko said.
