The IDF said it's carried out 10,000 airstrikes in the Gaza Strip.
The temporary cease-fire between Hamas and Israel ended early Friday, and Israel has resumed its bombardment of Gaza.
The end of the cease-fire came after Hamas freed over 100 of the more than 200 people its militants took hostage during the Oct. 7 surprise attack on Israel. In exchange, Israel released more than 200 Palestinians from Israeli prisons.

The latest outbreak of war between Israel and Hamas, the Palestinian militant group that governs the Gaza Strip, has passed the four-month mark.
In the Gaza Strip, at least 30,228 people have been killed and 71,377 others have been wounded by Israeli forces since Oct. 7, according to Gaza's Hamas-controlled Ministry of Health.
In Israel, at least 1,200 people have been killed and 6,900 others have been injured by Hamas and other Palestinian militants since Oct. 7, according to the Israel Defense Forces.
There has also been a surge in violence in the Israeli-occupied West Bank. Israeli forces have killed at least 395 people in the territory since Oct. 7, according to the Palestinian Ministry of Health.
The ongoing war began after Hamas-led militants launched an unprecedented incursion into southern Israel from neighboring Gaza via land, sea and air. Scores of people were killed while more than 200 others were taken hostage, according to Israeli authorities. The Israeli military subsequently launched retaliatory airstrikes followed by a ground invasion of Gaza, a 140-square-mile territory where more than 2 million Palestinians have lived under a blockade imposed by Israel and supported by Egypt since Hamas came to power in 2007. Gaza, unlike Israel, has no air raid sirens or bomb shelters.
Israel will no longer hold fire as negotiations with Hamas progress, an Israeli security source told ABC News on Friday.
The source said Israeli forces will only cease-fire for 24 hours if Hamas sends a list of at least 10 hostages to be released, the list is approved by Israel and everyone on that list is safely returned home.

United Nations High Commissioner for Human Rights Volker Turk warned Friday that the resumption of hostilities between Israel and Hamas in the Gaza Strip is "catastrophic," with the situation now "beyond crisis point."
"I urge all parties and states with influence over them to redouble efforts, immediately, to ensure a ceasefire -- on humanitarian and human rights grounds," Turk said in a statement.

Qatar announced Friday morning that efforts to renew a truce between Israel and Hamas "are continuing," despite the resumption of Israeli bombardment in the Gaza Strip.
Qatar, along with Egypt and the United States, have mediated the talks between Israel and Hamas.
"The State of Qatar expresses its deep regret at the resumption of the Israeli aggression against the Gaza Strip following the end of the humanitarian pause, without reaching an agreement to extend it," the Qatari Ministry of Foreign Affairs said in a statement. "The Ministry of Foreign Affairs confirms that negotiations between the two sides are continuing with the aim of returning to a pause. It also clarifies that the State of Qatar is committed, along with its mediation partners, to continuing the efforts that led to the humanitarian pause, and will not hesitate to do everything necessary to return to calm."
"The Ministry stresses that the continued bombing of the Gaza Strip in the first hours after the end of the pause complicates mediation efforts and exacerbates the humanitarian catastrophe in the Strip, and in this context calls on the international community to move quickly to stop the violence," the statement continued. "The State of Qatar reiterates its condemnation of all forms of targeting civilians, the practice of collective punishment, and attempts to forcibly displace and displace citizens of the besieged Gaza Strip, and its demand for an immediate ceasefire and to ensure the continuous and unhindered flow of relief convoys and humanitarian aid, in a way that meets the actual needs of the residents of the Strip."

U.S. Secretary of State Antony Blinken departed Tel Aviv on Friday morning at 7:45 a.m. local time as the cease-fire between Israel an Hamas ended and the two sides exchanged rocket fire.
When Blinken left, Hamas and Israel were still indirectly communicating on hostages. But Hamas had not handed over a list of potential releases when hostilities resumed. The Palestinian militant group, which rules the neighboring Gaza Strip, alleged it doesn't have any women or children left among its hostages to release. But Israel doesn't believe Hamas and also wants to see men and soldiers freed as well.
So far, Hamas has not provided a list of potential releases for Friday.
After landing in Dubai, Blinken did not answer shouted questions from reporters on the tarmac about the end of the temporary truce. But a senior official with the U.S. Department of State expressed hope a pause in hostilities could be reinstated as soon as the end of the day.
When asked about a report by The New York Times alleging Israel knew about Hamas' attack plan a year in advance, the official told reporters that it was clear there was a massive intelligence failure and there needs to be a reckoning. The official added that Israel will do an inquiry but its leadership is trying to delay it.
