MOSCOW (AP) — The Russian military has launched a massive exercise to simulate a response to possible security threats in Central Asia.

Defense Minister Sergei Shoigu said the five-day drills that began Monday will "check the armed forces' ability to ensure security in the Central Asian region that faces serious terrorist threats."

Russian officials have voiced concerns about the possible spread of militants from Afghanistan into former Soviet nations in Central Asia.

Russia has a military contingent in Tajikistan that borders Afghanistan and an air base in Kyrgyzstan.

Shoigu said that the maneuvers will be held at 35 firing ranges. He added that they will check the troops' capability to fend off terrorist threats and protect government facilities.
