"The Russian Defense Minister Gen. Sergei Shoigu has departed for a working visit to Iran. The defense minister is set to hold trilateral talks with his counterparts from Syria and Iran during his visit to Tehran. Immediate measures to strengthen cooperation between defense ministries in the fight against Daesh and the Nusra Front terrorist groups will be discussed," Antonov told reporters.
Shoigu will also attend a number of bilateral meetings with Iranian and Syrian military officials, where issues of regional security and military and technical cooperation will be dealt with, he added.
The Islamic State and the Nusra Front are militant Jihadist groups operating in Syria and outlawed in many countries, including Russia.
