The IDF has maintained a high alert level in North following suspicions that Syria might attack Israel or other Jewish targets around the world through the use of international terror networks, Israel Radio reported.
IAF jets were alerted twice over the last few days following then-suspicious activity in the Golan Heights. On Saturday a Syrian aircraft disappeared from the air force's radar screens, prompting the IAF to send planes to the Golan. It became apparent several minutes later that the Syria plane had crashed in its country's territory.
On Thursday, fighter jets were dispatched to the Golan when "suspicious activity" was reported in the area, the military officials said. Later it was discovered that the objects in the air were migrating birds, the officials said.
