The IDF says Hamas was using the schools as command centers and hiding places.
As the Israel-Hamas war continues, tensions are escalating after the assassinations of two Hamas and Hezbollah leaders this week.
Hamas is calling for a day of marches of rage around the world on Friday in condemnation of the Israeli assassination of political leader Ismail Haniyeh and the ongoing killing of Palestinians in the Gaza Strip.
Hamas also called for absentee funeral prayers for Haniyeh.
Hundreds of thousands of people are expected to take part in the day of rage.
Thousands of people gathered for Hezbollah commander Fouad Shukr's funeral, including the top leader of Hamas in Lebanon. Hezbollah’s secretary general, Hassan Nasrallah, appearing via video, told the crowd that a response to Shukr’s killing is coming. He said there is no discussion about the retaliation -- adding that it will be big.
The main streets of Dahiya are lined with photos of Shukr, who was killed in an Israeli airstrike on Beirut Tuesday evening.
In the hours leading up to Thursday's ceremony, the growing crowd often chanted "Death to Israel," "America is the great Satan" and "Death to America!"
"It’s not the death of the citizens. It’s not the death of the innocents. It’s the death of the hypocrisy. Of the arrogance. And of the oppression," an unidentified man in the audience shouted at reporters.
After Nasrallah’s speech, Shukr’s yellow flag-draped casket was carried through the streets of Dahiya and to a burial site. Many people lined either side to pay their respects.
Speaking at the funeral of Hezbollah commander Fouad Shukr, Hezbollah leader Hassan Nasrallah said Israel has crossed a line, warning there will be rage and revenge.
Thousands of people lined the streets of Beirut to mourn Shukr.
Nasrallah said Hezbollah entered the battle believing its morality, legitimacy and importance, adding they are now in an open battle on all fronts that has entered a new phase.
Nasrallah denied responsibility for the Majdal Shams attack, which Israel and the U.S. have said came from Hezbollah. He also commented on the Israeli assassination of Hamas' political leader, Ismail Haniyeh, in Tehran, Iran, hours after Shukr was targeted in a strike on Beirut warning Iran will likely respond.
Throngs of people flooded the streets of Tehran on Thursday for the funeral procession of Ismail Haniyeh, the Hamas political leader who was assassinated early Wednesday.
Iran's supreme leader, Ayatollah Ali Khamenei, led funeral prayers over the bodies of Ismail Haniyeh and his bodyguard, who was also killed.
Haniyeh was killed in Tehran, the Iranian capital. His remains are expected to be transferred to Qatar, where he had lived in exile since 2019, for burial on Thursday.
No country or organization has yet taken credit for the assassination, but Khamenei appeared on Tuesday to place the blame on Israel. He said it was Iran's "duty to take revenge."
