Announcement from the military spokesman for Al-Qassam Brigades, Abu Ubaida:

Every price we pay, and we will pay it as a debt for Jerusalem. It is not strange that a group of Al-Qassam heroes rose in this battle, headed by the remarkable commander Basem Issa.
To the enemy: The whole world has seen your disappointment and disgrace. Gather what you want from your forces on land, sea and air, for we have prepared for you varieties of death that will make you curse yourselves.
The decision to bomb Tel Aviv, Jerusalem, Dimona, Ashkelon, Ashdod, Beersheba and before and beyond… it is by God easier for us than drinking water.
