A top U.N. official warned Thursday of another potential conflict in the Gaza Strip, urging Israel to lift its blockade and the Palestinians to end in-fighting to avoid further violence.

The United Nations also called for an additional $705 (622 million euros) million in humanitarian aid to the Palestinian territories, most of it for Gaza which saw its bloodiest and most destructive war last year.

Hatem is only 14 but has already lived through three wars with Israel. Now the young Gazan says he is making sure he'll be ready to fight in the next one.

"The Israelis killed my niece last summer. Now I want to kill them," he told Agence France Presse after completing a week-long youth training camp with militants from the Ezzedine al-Qassam Brigades, the armed wing of the Islamist Hamas movement.

A senior aide to Palestinian President Mahmoud Abbas took the stand Sunday in the trial of exiled Gaza strongman Mohammed Dahlan who is being tried in absentia on corruption charges. 

The trial of Dahlan, once a leading figure in Abbas' Fatah movement who headed Gaza's powerful security forces, began in December. 

A bomb blew up the car of an official with the Palestinian Islamist movement Hamas in Gaza, the second such attack in recent weeks, a security source said Saturday.

The blast, which occurred late on Friday night but caused no casualties, comes as political tensions mount in the Palestinian territory.

Hundreds of Palestinians demonstrated outside Egypt's diplomatic mission in Gaza City Friday, to protest a Cairo court ruling designating Hamas's armed wing as a terrorist group.

They waved green Hamas flags and chanted in support of the Ezzedine al-Qassam Brigades: "Qassam are the pride of the nation, not terrorists!"

A Palestinian journalist who also works as advisor in the Gaza Strip to Dutch diplomats was kidnapped and beaten by men claiming to belong to the Islamic State group, a relative said Wednesday.

Mohammed al-Maghayer went missing Tuesday morning and was released several hours later after having been interrogated about his links to the Dutch, the relative said.

Hamas accused Egypt's army of firing at Palestinian security outposts in the Gaza Strip Tuesday, just days after Cairo declared the Islamist movement's military wing a terrorist group.

Gaza's Hamas-run interior ministry condemned "the Egyptian army for firing this morning directly at two positions along the southern Gaza border."

Israel called Tuesday for the shelving of a U.N. inquiry into its war last summer in the Gaza Strip after the probe's head quit over Israeli accusations of conflict of interest.

Canadian international law expert William Schabas resigned Monday after Israel complained that he had prepared a legal opinion for the Palestine Liberation Organization in October 2012, the United Nations said.

Hundreds of Hamas supporters marched in the Gaza Strip on Monday to protest an Egyptian court decision to declare the Islamic movement's armed wing as a banned "terrorist" group.

Waving the green flag of the movement, which is the de facto power in the coastal Palestinian territory, demonstrators chanted "Hamas is not terrorist" and "Hamas is our pride" during the rally in the northern Gaza town of Jabaliya.

The war between Israel and Gaza drove the Palestinian economy of Gaza and the West Bank into its first contraction since 2006, the International Monetary Fund said Thursday.

While the West Bank managed a 4.5 percent expansion last year, Gaza's economic activity declined by about 15 percent, the IMF said, linking it to Israel's harsh bombing and shelling of the Gaza enclave and slow progress on rebuilding.
