Three remaining members of a Palestinian delegation negotiating a longer-term truce in Gaza were on their way to Cairo Tuesday after entering Egypt through the Rafah crossing, state media reported.

Israel and Hamas halted their fighting in Gaza from 0500 GMT Tuesday after a three-day temporary truce brokered by Cairo went into effect. Israel also withdrew its troops from the coastal enclave.

Waving her son goodbye as he boarded a bus carrying his unit away from Israel's border with Gaza, Orly Doron was relieved but apprehensive about the lull in fighting Tuesday.

Doron comes from Kfar Aza kibbutz close to Gaza, where her son has been involved in the intense fighting that has left areas of the Palestinian enclave in ruins.

Twenty-nine days of fighting between Israel and Hamas broke out on July 8 and expanded with an Israeli ground assault nine days later. A truce came into effect Tuesday.

Here is a summary of the chief statistics as the 72-hour ceasefire began:

A Foreign Office minister who was the first Muslim to sit in the British cabinet dramatically resigned on Tuesday over what she called the government's "morally indefensible" policy on Gaza.

The surprise decision by Baroness Sayeeda Warsi, who also had responsibility for faith and communities, heaped pressure on Prime Minister David Cameron to take a tougher line against Israel over its actions in Gaza.

A 72-hour truce took hold in Gaza on Tuesday as Israel withdrew troops following four weeks of bitter fighting and Palestinians ventured out to find scenes of destruction.

The guns fell silent after 29 days of fighting, bringing relief to millions as both sides counted the cost from a conflict that killed at least 1,867 Palestinians and 67 people in Israel.

United Nations Secretary-General Ban Ki-moon urged "utmost restraint" after Israel and Hamas agreed to begin a new, 72-hour truce Tuesday in their bloody, month-old conflict.

The breakthrough came during talks in Cairo on Monday, only days after a similar three-day agreement to let the guns fall silent collapsed in a deadly wave of violence within hours of starting on Friday.

A rocket was fired from southern Lebanon on Monday towards Israel, but missed its target and hit Lebanese territory instead.

"A rocket was fired a while ago from a region between al-Jormoq and al-Zafata (in the South),” the state-run National News Agency reported on Monday evening.

Britain is reviewing licenses to sell arms and military goods to Israel in the light of ongoing operations in Gaza, Prime Minister David Cameron's office said Monday.

Britain's government has approved licenses for the sale of military goods to Israel worth at least £42 million ($71 million, 53 million euros) since 2010, according to government figures obtained by the Campaign Against Arms Trade (CAAT).

Human Rights Watch on Monday accused Israel of killing civilians as they attempted to flee a stricken neighborhood of Gaza, in what it said would amount to a war crime.

In a report that cited Palestinians who managed to get out of Khuza'a, HRW said the attacks on the town near the southern city of Khan Yunis occurred at the end of July.

One Israeli was killed and five others injured Monday when an excavator rammed into a Jerusalem bus, turning it over before the driver was shot dead by police, officials said. 

The incident took place on the seamline between east and west Jerusalem and came as Israel pressed a major military campaign in Gaza which has killed more than 1,800 Palestinians.
