A series of explosions on Tuesday in an abandoned building near Lebanon's tense border with Israel was the result of a fire in a Hizbullah weapons depot, according to a Lebanese security official.
There were no casualties in the blasts, though widespread panic was caused among residents, some of whom mistook it for an Israeli air raid.
The depot in the village of Khirbet Silim, about 10 miles north of the border, was housed in an abandoned building and was likely used during the 2006 Second Lebanon War, added the official, speaking on condition of anonymity in line with military regulations.
Lebanese soldiers and firefighters sealed the area off after the explosions to keep journalists away.
The Lebanese army issued a statement saying only that the area was sealed after an explosion in an abandoned building and that a joint committee from the military and UN peacekeepers was investigating.
