In a scathing reaction to Netanyahu's speech, Lebanon's acting foreign minister Gebran Bassil suggested that Israel had forgotten its previous defeats at the hands of Lebanese forces.
"Here is Israel once again coming up with excuses to justify aggression and preparing to violate the sovereignty of other nations using the [UN] platform," Bassil tweeted.
"Israel has forgotten that Lebanon drove it out, defeated its aggression, and seems oblivious to the fact that its arrogance and 'new friends' will be of no benefit," the foreign minister added, referring to Prime Minister Netanyahu's remark about Israel gaining a new "intimacy and friendship" with other Arab states against Iran.
Netanyahu also implicated Iran with "directing Hezbollah to build" these secret sites in a bid to "convert inaccurate projectiles into precision-guided missiles…that can target deep inside Israel with an accuracy of 10 meters."
"I have a message for Hezbollah today. Israel knows what you're doing, Israel knows where you're doing it, and Israel will not let you get away with it," Netanyahu warned.
The Israeli prime minister's comments echoed remarks he made last week, when he warned that Hezbollah would be dealt a "crushing blow" if it tries to "confront" Israel.
