Dozens killed, hundreds injured after Hamas sends rockets, fighters in to Israel, which has started bombing Gaza.

Here is what to know:

What happened and when?

• The Palestinian armed group Hamas has launched “Operation Al-Aqsa Flood” against Israel in the most serious escalation since Israel and Hamas fought an 11-day war in 2021.
• Hamas said it had fired 5,000 rockets, while Israel confirmed that the group’s fighters had entered its territory.
• Daniel Hagari, an Israeli army spokesman, said that the group attacked from land, sea and air.
• The first round of rockets was fired at 06:30am local time (03:30 GMT).
• The Israeli army also said it launched “Operation Iron Swords” against the Hamas group in the Gaza Strip.
• The early-morning strikes occurred on Simchat Torah, a holiday which falls towards the conclusion of the weeklong Jewish festival known as Sukkot, or the Feast of Tabernacles.

Where did the attacks take place?

• The rockets were fired as far north as Tel Aviv. Hamas also sent fighters into southern Israel.
• Israeli media said that gunmen had opened fire on passers-by in the town of Sderot, and footage circulating on social media appeared to show clashes in city streets as well as gunmen in jeeps roaming the countryside. One report claimed Hamas fighters had taken control of multiple Israeli civilian population centres, where residents were begging for help from their government.
• The Israeli army says dozens of fighter jets were carrying out attacks on Hamas targets in the Gaza Strip.
• Currently, the gun battles are taking place in and around the towns of Kfar Aza, Sderot, Sufa, Nahal Oz, Magen, Be’eri, and the Re’im military base, the Times of Israel reported.

How many casualties in Israel and Palestine?

• At least 22 Israelis have been killed, local media said, quoting emergency services. More than 500 Israelis have been injured, Reuters quoted the country’s health ministry as saying.
• At least four Palestinians have been killed and five are wounded in confrontations between the Israeli army and Palestinian groups in the border area of the Gaza Strip, Anadolu news agency said.

Why did Hamas attack Israel?

• Hamas spokesperson Khaled Qadomi has told Al Jazeera that the group’s military operation is in response to all the atrocities the Palestinians have faced over the decades.
• “We want the international community to stop atrocities in Gaza, against Palestinian people, our holy sites like Al-Aqsa. All these things are the reason behind starting this battle,” he said.

• “This is the day of the greatest battle to end the last occupation on earth,” Mohammed Deif, the Hamas military commander said, adding that 5,000 rockets were launched.
• “Everyone who has a gun should take it out. The time has come,” Deif said, according to reports.
• Hamas called on “the resistance fighters in the West Bank” as well as “our Arab and Islamic nations” to join the battle, in a statement posted on Telegram.

What is the Israeli government saying?

• The Israeli army warned Israelis who live near Gaza to stay in their homes or head to shelters.

• “In the last hour, the Hamas terrorist organisation had begun a massive shooting of rockets from the Gaza Strip into Israeli territory, and terrorists infiltrated into Israeli territory in a number of different locations,” the army said. “The Hamas terrorist organisation is the sovereign in the Gaza Strip and is responsible for this attack. It will face the consequences and responsibility for these events,” it added.
