An official says an area of the Czech Republic where the military once planned to install advanced radar as part of a U.S. missile defense system will now become a nature reserve.

The Bush administration had proposed stationing 10 interceptor missiles in Poland and the advanced radar in the Czech Republic, saying the system was aimed at blunting future missile threats from Iran. But Russia angrily objected and warned that it would station its own missiles close to Poland if the plan went through.

In September 2009, the Obama administration shelved that plan.

Czech Defense Minister said Wednesday that since the military now only uses the scenic Brdy area southwest of Prague for artillery training four days a year, it will become a protected nature reserve in 2016.
