The Israeli military says it has collected information on nearly 1,000 bunkers, arms facilities and listening posts built by the militant group Hezbollah in Lebanon.
Israel released a map of the sites to the media on Thursday.
Israeli officials say some of the sites are in an area of southern Lebanon, close to Israel, where Hezbollah is banned from storing weapons under a 2006 U.N.-sponsored truce between Hezbollah and Israel.
In all, Israel claims Hezbollah has about 550 bunkers, 300 monitoring sites and 100 weapons storage facilities.
The Associated Press reported that a Hezbollah official, Khodr Noureddine, a member of Hezbollah's political bureau did not comment on the map but accused Israel of inflaming war talk.
Israel maintains that Hezbollah is rearming with aid and weapons from Iran and Syria. Hezbollah launched some 4,000 rockets into northern Israel during the 2006 war
The war killed at least 1,200 Lebanese and 160 Israelis, according to official counts.
