Five Palestinians were moderately injured by shelling in the nearby border town of Khuzaa, Gaza health ministry spokesman Ashraf al-Qidra told Maan news agency on Monday. Later Monday morning, residents said a missile was fired at Rafah by an Israeli military aircraft, with no reports of casualties.

In a statement released Monday, the IDF spokesperson said that the IDF hit “a number of terror cells and targets of the terrorist organization Hamas in the Gaza Strip, in response to the rockets fired this morning toward territory of the state of Israel,” 
Haaretz reported.

Israel said up to 30 rockets had hit southern Israel early Monday, with no immediate reports of injuries of damage.

At the same time, Hamas’ military wing Izz Addin Al-Qassam Brigades and the Islamic Jihad’s Al-Quds Brigades in an unusual move claimed responsibility for the fire, saying they were targeting Israeli military bases in response to an air strike on Sunday.

Hamas has not claimed responsibility for launching rockets and mortars at Israel since June.

On Sunday evening, an Israeli air strike on a motorbike in Rafah in the southern Gaza Strip injured eleven Palestinians, including five children. Israel’s army said it had targeted two jihadi militants.

“Going too far in the aggression on the Gaza Strip will provoke the Palestinian resistance into responding more strongly and on a wider scale,” a statement released on Monday by Qassam Brigade spokesman Abu Ubayda said.

Gaza’s Hamas leadership and the Islamic Jihad faction confirmed the ceasefire with Al Jazeera on Tuesday, after four days of Israeli attacks. Israel accuses Palestinian factions of firing rockets into the country.

The latest round of violence began on Friday after Israel killed Zuhair Al-Qaisi, head of the Popular Resistance Committees, prompting militant groups to begin lobbing rockets over the border. The army said Qaisi had planned a deadly attack in August 2011 and accused him of planning a repeat attack “in the coming days.”

“We accept a ceasefire if Israel agrees to apply it by ending its aggressions and assassinations,” according to Daud Shehab, an Islamic Jihad spokesman said.

The United States welcomed the truce.”There are reports that the Egyptians have been able to negotiate some calm. If, in fact, that’s the case, that would, of course, be very welcome,” State Department spokeswoman Victoria Nuland said in Washington according to AFP news agency.

Home Front Defence Minister Matan Vilnai told public radio, Israel had reached an “understanding” with militant groups in Gaza

The Palestinians and Israelis made rival calls Sunday for the UN Security Council to act as the international Quartet on the Middle East -the United States, European Union,United Nations and Russia -holds its first top-level meeting in six months on Monday.

Riyad Mansour, the Palestinian envoy to the UN, said the Security Council must “act with urgency to address this crisis,” accusing Israel of staging an “escalation of deadly violence and terror.”

In return, Israel criticised the international community’s “silence” over rocket attacks from Gaza, and said in a letter to the Security Council that it would take “all necessary measures” to protect civilians against the renewed barrage.
