A Russian military adviser has been killed in Syria after the Syrian army unit, which he was attached to, came under mortar fire. He is the third Russian soldier to die during the Syrian campaign.

The adviser, whose name and rank were not disclosed by the Defense Ministry, was killed on Monday, the ministry said in a statement. He was deployed to a Syrian army unit to train the troops in the use of advanced weapons, which Russia delivered to Syria as part of its antiterrorist effort, according to Russia Today.

The fatality is the third in Russia’s campaign in Syria, which started in September last year. In November 2015, two troops were killed in an incident involving Turkey’s downing of a Russian bomber plane.
