The Lebanese army says it has dismantled two "espionage" devices that had been planted by Israel.
The army released a statement Wednesday that said one device had been placed on the Sannine mountain, which overlooks Beirut, while the other device was on the Barouk mountain, south of the capital.
The army said the mount Sannine device had visual emission and reception components. It said the other device was a "more complicated system," but did not elaborate.
There was no immediate response from Israel.
The statement said Hezbollah alerted the army about the devices. Hezbollah leader Hassan Nasrallah said Israel is working on collecting intelligence on the "brothers" in Lebanon as well as Syria, Iran and in Palestinian areas. He commented in a Wednesday speech marking the eve of Ashura, a Shi'ite religious observance.
Tensions between Israel and Hezbollah militants have been high since the two sides engaged in a 2006 war that killed more than 1,300 people, most of them Lebanese.
