Palestinian woman captures the moment powerful blasts hit Gaza as Israel continues unprecedented bombardment in revenge for Hamas attack

A Palestinian woman captured heavy explosions on video while filming life under siege in Gaza.

Israel is pounding the region with rockets after Hamas fighters launched an unprecedented attack on Israel at the weekend in clashes that left nearly 1,000 Israeli's dead.

The woman decided not to leave her home and describes the measures residents are taking in an attempt to avoid Israel's missiles.

Palestinians reported receiving calls and mobile phone audio messages from Israeli security officers telling them to leave areas mainly in the northern and eastern territories of Gaza, and warning that the army would operate there.

Dozens of people in Gaza City's Remal neighbourhood fled their homes.

During the video, the woman is interrupted by ear-splitting explosions before saying she needs to check her parents are safe.

"We are inside the house right now but we literally can't breathe," she said while showing the view from her balcony which revealed the area covered in dust and ash.

Israeli TV channels said the death toll from the Hamas attack over the weekend had climbed to 900 Israelis, with at least 2,600 injured, and dozens taken captive.

Israel has called up an unprecedented 300,000 reservists and imposed a blockade on the Gaza Strip, raising fears a ground assault could take place.

The violence, which has claimed more an estimated 1,500 lives in total, prompted international declarations of support for Israel and appeals for an end to the fighting.

Among the Israeli dead were 260 mostly young people massacred at a music festival where some of the hostages were abducted.

Israeli Prime Minister Benjamin Netanyahu vowed revenge in a fiery speech accusing Iran-backed Hamas of executing tied-up children and other atrocities: "This vile enemy wanted war and it will get war," he said.

Israel also bombed the headquarters of the private Palestinian Telecommunication Co., which could affect landline telephone, internet and mobile phone services.

The strikes continued into Monday night. The Israeli military said it hit targets in the Gaza Strip from the sea and air, including a weapons depot it said belonged to Islamic Jihad.

Washington - which provides Israel with $3.8 billion in military assistance each year - said it was sending in fresh supplies of air defenses, munitions and other security assistance to Israel.

The United States' top general warned Iran not to get involved in the crisis and said he did not want the conflict to the broaden. Iran makes no secret of its backing for Hamas and has applauded the weekend attack while denying any involvement.

"We want to send a pretty strong message. We do not want this to broaden and the idea is for Iran to get that message loud and clear," General Charles Q. Brown, the chairman of the Joint Chiefs of Staff, told reporters traveling with him to Brussels.

Governments including Italy, Thailand and Ukraine reported that their citizens had perished in the Hamas attacks. In Washington, President Joe Biden announced that at least 11 Americans had been killed and it was likely U.S. citizens were among those held hostage.
