Lebanon’s President Michel Aoun warned on Friday that Israel would bear the results of any attack.
Aoun's statement comes days after a flare-up at the border between Israel and Iran-backed Hezbollah.
The frontier between the two countries has remained calm since Israel and Lebanon’s Hezbollah traded fire on Sunday, Reuters reported.
Israel’s military said it had responded with fire into south Lebanon after anti-tank missiles targeted an army base and vehicles.
Hezbollah said its they destroyed an Israeli armored vehicle, killing and wounding those inside, however, Israel said there were no casualties.
Hezbollah leader Sayyed Hassan Nasrallah said this week that the episode had ended but had launched a “new phase” in which they would target Israeli drones that breach Lebanon’s airspace.
According to Reuters, Aoun has likened the crash of the drones, including one that exploded, to a “declaration of war”.
“Any attack on Lebanon’s sovereignty ... will be met with legitimate self-defense which Israel will bear all the consequences of,” Aoun’s office cited him as saying on Friday in a meeting with UN Special Coordinator for Lebanon Jan Kubis.
