Israeli warplanes have conducted air strikes along the border with Lebanon as the militant Hezbollah group attacked several Israeli army posts, including one that was struck with two large rockets.

The escalation came a day after Hezbollah leader Hassan Nasrallah said his powerful group is already engaged in unprecedented fighting along the Lebanon-Israel border.
