Hezbollah says it hit Israeli post with 62 rockets

Hezbollah said on Saturday that it hit an Israeli observation post with 62 rockets as a "preliminary response" to the killing of Hamas's deputy chief earlier this week.

An Israeli drone strike in a southern suburb of Beirut killed senior Hamas official Saleh al-Arouri on Tuesday.

Hezbollah chief Hassan Nasrallah said on Friday that all of Lebanon would be vulnerable to further attacks if the group remained "silent" on the strike. 

The group hit a key post on a hilltop that Israel relied on for "aerial observation" and "air control", according to Hezbollah's statement early on Saturday.

Earlier in the day, Israel's military said heavy fire from Lebanon targeted northern Israel, adding that it responded by striking a "terrorist cell" that took part in the attacks.

Shortly after rocket sirens sounded across northern Israel, the military said "approximately 40 launches from Lebanon toward the area of Meron in northern Israel were identified".
