The loud blast that sounded in Lebanon Wednesday night was the result of an Israeli operation aimed at destroying espionage equipment planted off the coast of Sidon, a Lebanese radio station reported Thursday.
On Wednesday the Lebanese army announced it had uncovered Israeli cameras and other spy equipment in the mountainous region, which it claimed the state had been using in order to survey vast areas.
The army statement said long range spying systems were placed in Sanin Mountain and the Barouk mountains, which overlook the capital of Beirut. It added that Hezbollah had provided the information leading to the find.
Later, Lebanese media outlets reported a major explosion off the coast of Sidon. They said the blast was accompanied by over-flights conducted by the Israeli air force in the area and the launching of illuminating bombs.
Lebanese Prime Minister Saad Hariri condemned the alleged infiltration of Israeli aircraft into his country's territory, saying it "stirred panic among the residents of Sidon and south Lebanon."
Hariri called on the UN to act against "attacks on Lebanon's sovereignty."
