The cease-fire took effect at 3pm (8am ET).

Israel Defense Forces (IDF) said it monitored a Qassam rocket attack on Saturday night that appeared to come from the vicinity of the Jabiliya refugee camp. A retaliatory airstrike was launched, and the target, a militant cell of three men, was believed destroyed, the IDF said.

There was no immediate word from the Palestinians on casualties.

Earlier on Saturday, three Qassam rockets were fired into Israel, one of which damaged a building in a town south of Sderot. On Friday, officials said, 17 rockets were fired into Israel from Gaza.

Israel Defense Forces carried out two airstrikes on Friday night. One targeted two sites used to manufacture weaponry; the other, south of Beit Hanoun, targeted a group of militants believed to have launched a Qassam rocket on Sderot.

Palestinian medical sources said two Palestinian civilians were killed and four wounded in the second airstrike.

In the latest effort to quell the Palestinian internal fighting, Palestinian Authority President Mahmoud Abbas will visit Gaza "in the next few days" to meet with Palestinian Prime Minister Ismail Haniyeh, according to chief Palestinian negotiator Saeb Erakat. Abbas is a member of Fatah, while Haniyeh is a member of Hamas.
