A United Nations investigation into recent explosions in South Lebanon have indicated that Israel had planted spy devices on Lebanese land in violation of a ceasefire agreement. It appears the spy devices were detonated by remote control from Israel after their discovery by Lebanese security forces. A first explosion was reported on Saturday evening and a second on Sunday morning. No injuries were reported. If confirmed, the devices would represent violations of Security Council Resolution 1701, which halted the 2006 war in Lebanon. Meanwhile, Israel is also being accused of flying drones over Lebanon. Michael Williams, the UN special coordinator for Lebanon, said the use of drones was an obvious violation of Lebanese sovereignty and Resolution 1701.
