A man allegedly shouting "death to Arabs" stabbed and wounded an Arab Israeli on Monday in the town of Herzliya near Tel Aviv, police said.

Spokeswoman Luba Samri said in a statement that police arrested a local Jewish Israeli suspected of the attack, in which a municipal cleaner from the Galilee village of Kafr Manda was lightly injured.

Israeli Prime Minister Benjamin Netanyahu was on Monday given a 14-day extension to form a new government as he struggles to build a coalition after four weeks of intensive talks.

Such a move is far from unusual in Israel where it is almost unheard of for a single party to win an outright majority, and lengthy negotiations with multiple potential coalition partners are the norm. 

An Egyptian court Sunday sentenced to jail a man convicted of spying for Israel in the Sinai Peninsula where security forces are fighting an Islamist insurgency, judicial officials said.

Two Israeli accomplices of the jailed Egyptian were tried in absentia and also given life terms, the officials added.

The mayor of Haifa, Israel's third largest city, ordered Sunday the closure of five petrochemical plants following a health ministry warning linking high cancer rates to air pollution. 

Haifa Mayor Yona Yahav further said that municipality trucks were blocking the entrances to Israel Oil Refineries and Petroleum & Energy Infrastructures, both of which are based on the bay in the northern port city. 

Israeli Prime Minister Benjamin Netanyahu is to make a formal request for extra time to piece together a new government, the president's office said Sunday.

After a surprise election victory, Netanyahu was on March 25 tasked by President Reuven Rivlin with forming the next government and given four weeks to do so. 

An explosive device was detonated outside the U.N. agency for Palestinian refugees in Gaza City overnight, without causing any injuries, U.N. and Palestinian security sources said late Saturday. 

"A bomb exploded near the outer wall of UNRWA's headquarters in Gaza, some 10 metres (yards) from the gate, without causing any injuries or damage," agency spokesman Adnan Abu Hasna told Agence France Presse. 

A Palestinian driver deliberately rammed his car into a Jerusalem bus stop this week and killed an Israeli man in a "horrible attack", police chief Yohanan Danino said on Saturday.

"Today we can say that it is a horrible attack," Danino said in a statement after an investigation into Wednesday's incident.

Protesters clashed with Israeli troops in the northern West Bank on Friday during annual demonstrations marking Palestinian Prisoners Day, an AFP correspondent said.

More than 100 Palestinians rallied near Israel's separation barrier in the village of Bilin, with some throwing stones before soldiers opened up with tear gas to disperse the crowd.

Israeli Prime Minister Benjamin Netanyahu was holding talks Friday with potential partners to form a coalition government, less than three weeks from a deadline to form a new cabinet.

Netanyahu was meeting separately with Foreign Minister Avidgor Lieberman, head of the ultra-nationalist Yisrael Beitenu, and with Naftali Bennett, of the far-right Jewish Home.

Hadi al-Fakhri was 26 the first time he hugged his father, one of thousands of Palestinians serving time in Israeli prisons for militant activity in the occupied West Bank.

A decade later, more than 30 years into a life sentence, Fakhri's father was freed when more than 1,000 prisoners were swapped for a single Israeli soldier held by Palestinian Islamist group Hamas for five years.
