The Israeli Air Force conducted the massive airstrike targeting the headquarters, built underground beneath residential buildings, in the heart of the Dahiyeh district of the Lebanese capital on Friday evening.

The pilot said, 'We will do everything necessary to bring the hostages home and return the residents of the north home.'

Al-Arouri is the commander of Hamas operations in Judea in Samaria.

'We share the pain of the Lebanese people and sincerely reach out to offer our aid at this difficult time,' Israeli President Reuven Rivlin commented after the deadly explosion.

Huge blasts tore through Beirut on Tuesday, causing dozens of deaths and thousands of injuries.
