LVIV, Ukraine, Sept. 15 (UPI) -- About 1,300 troops from 15 NATO countries, including about 200 U.S. troops, are in Ukraine to participate in a military exercise.
The 10-day exercise, called Rapid Trident, also involves an unspecified number of Ukrainian troops, and begins Tuesday in Lviv, near Ukraine's border with Poland and about 600 miles from Donetsk, where pro-Russian separatists are engaged in fighting the Ukrainian army. The activity was planned for July, but postponed because of the conflict in eastern Ukraine.
