IDF Military Intelligence rejects this allegation, saying that it had warned the political echelon of the threat of an attack by Hamas almost a month ahead of time, in mid-April, when significant clashes broke out regularly between residents of East Jerusalem and Israeli forces and amid the Palestinian Authority's decision to indefinitely postpone Palestinian elections that were planned for May.
According to an army spokesman, seven people have been killed by shelling in Israel so far.
The Gaza health ministry says the toll from the fighting has risen to 119 killed, including 31 children and 19 women, with 830 wounded.

U.S. President Joe Biden said Thursday that he doesn't believe Israel's onslaught against the besieged Gaza Strip this week has been a "significant overreaction", remarks that came shortly before the Israeli military escalated its assault on the densely populated territory with air and artillery attacks involving almost 200 war planes, tanks, and brigades of ground troops.
Within hours, Israeli warplanes began bombing militant targets in Gaza, with the military saying that civilian casualties "cannot be ruled out" in the densely populated coastal territory.

Clashes around the al-Aqsa mosque compound have seen Israeli police firing rubber bullets, tear gas and stun grenades inside what is the third holiest site in Islam.
