Palestinians Fired More Than 20 Rockets Into Israel From Gaza

Palestinian militants in Gaza fired more than 20 rockets into southern Israel, the heaviest bombardment since 2012.
Israeli Prime Minister Benjamin Netanyahu vowed to respond «strongly».
The attack comes a day after an Israeli air raid on Gaza that killed three members of the Islamic Jihad militant group.
The group said it fired the rockets to avenge these deaths.
The amount of rocket attacks into Israel declined since the military launched an eight day offensive against Gaza militants 16 months ago.
