According to the senior official, Russia has boosted its electronic warfare capability in Syria and monitors up to 200-km (124-mile) radius of airspace from where incursions had previously taken place.
"We have considerably strengthened electronic warfare capability. We dispatched additional equipment there. As a result, we control a short-range zone within a 50-km radius and a long-range zone — the main direction from where incursions were conducted — within a 200-km radius," Shoigu said.
