Lebanese armed group Hezbollah said it hit a key Israeli observation post early on Saturday with 62 rockets as a «preliminary response» to the killing of Hamas' deputy chief last week.
Senior Hamas official Saleh al-Arouri was killed on Tuesday, Jan. 2 in an Israeli drone strike on Beirut's southern suburb of Dahiyeh.
Analysts said the strike could be seen as a message to Hamas ally Hezbollah that even its prime stronghold of Dahiyeh could be vulnerable to Israeli attack.
Hezbollah had said his killing would not go without punishment.
