Caretaker Prime Minister Najib Mikati said Sunday that diplomatic efforts were ongoing to "stop Israeli attacks on Lebanon" and prevent the Gaza conflict from spilling into the country.
"Lebanon's friends are with us in continuing to make every effort to return the situation to normal," Mikati said in a statement.
However, Lebanon was developing an emergency response plan "as a precaution," he added.
Tit-for-tat attacks at the Lebanese-Israeli border have so far been relatively contained, but analysts have warned that the chances of Hezbollah scaling up involvement could hinge on any Israeli ground invasion of Gaza.
