MOSCOW, July 26 (Itar-Tass) - The Russian Investigative Committee has opened a criminal case in connection with shelling of Russia's territory from Ukraine, a committee official said.

The SK (Investigative Committee) authorities in the Southern Federal District have opened a criminal case on charges of attempted murder and an attack against law-enforcement officials, SK spokesman Vladimir Markin said.

On July 25, an investigative group, including SK officers, came under fire from Ukraine’s territory when examining an area west of the farm of Primiussky in Russia's Rostov region. The area bordering Ukraine was shelled from the Ukrainian side on July 23.

Intensive mortar fire was opened on the group of SK investigators when they were working. They were in uniform with identification marks, Markin said, adding the Investigative Committee was sure the attackers on the Ukrainian side intentionally aimed the fire at Russian law-enforcement officers.

It seems that only the Ukrainian military's poor training and the fast evacuation of the investigators under cover of armoured vehicles saved the people, he said.

A local girl was lightly contused in the attack. She was in the yard near her home.
