"We can also add our 12 heroes who are being illegally held on the territory of the neighboring country," he added.
The Ukrainian side treats all the terrorists' proposals on prisoner exchange 'with great patience,' Tandit said.
"We are quite patient and we ready for the formula offered by that side.
