By Nick Tattersall and Vladimir Soldatkin ISTANBUL/NIZHNY TAGIL, Russia (Reuters) - Russia sent an advanced missile system to Syria on Wednesday to protect its jets operating there and pledged its air force would keep flying missions near Turkish air space, sounding a defiant note after Turkey shot down a Russian fighter jet. The downing of the jet on Tuesday was one of the most serious publicly acknowledged clashes between a NATO member and Russia for half a century, and further complicated international efforts to battle Islamic State militants in Syria. President Tayyip Erdogan made no apology, saying his nation had simply been defending its own security and the "rights of our brothers in Syria".
Late Russian leader Boris Yeltsin's "nuclear button" briefcase went on display Wednesday as a major new museum devoted to the legacy of Russia's first president opened in the Urals. Russian President Vladimir Putin -- whom an ailing Yeltsin anointed as his heir on New Year's Eve 1999 with the words "Take care of Russia" -- unveiled the Boris Yeltsin Presidential Centre in the former leader's home city of Yekaterinburg in the Ural mountains. Putin called the museum a "tribute to the memory of Russia's first president" and the radical change the country went through in the 1990s.
