An Israeli reserves officer died on Thursday of wounds sustained in a rocket attack that occurred hours before a truce to end eight days of violence in and around Gaza was agreed between Israel and Hamas.

A statement from the Israeli army named the casualty as "Lieutenant Boris Yarmulnik, 28 years old from Netanya," who "died of his wounds... after a rocket fired from the Gaza Strip hit the Eshkol Regional Council (Wednesday) afternoon."

The Hamas prime minister of the Gaza Strip, Ismail Haniya, on Thursday called on all Palestinian factions to respect a truce deal reached with Israel a day earlier.

"I salute the resistance factions who have respected the agreement since it entered into force and I ask everyone to respect it and act accordingly," Haniya said in a Gaza City speech.

A Palestinian woman in her late 30s was arrested on Thursday after trying to stab an Israeli border guard at the entrance of an east Jerusalem police station, police said.

It was not immediately clear what prompted the woman to attack the border guard, who suffered only scratches, a statement said, indicating that an investigation was under way.

Life in Gaza began returning to normal on Thursday with a public holiday to mark a ceasefire that ended a violent eight-day confrontation with the Israeli military.

After days and nights cooped up at home, their buildings rocked by an unrelenting Israeli bombing campaign and the sound of outgoing Palestinian rocket fire, residents were eager to reclaim their hometowns and their lives.

Israeli troops arrested 55 Palestinian "terror operatives" across the West Bank overnight, hours after a truce came into effect in the Gaza Strip, the army said on Thursday.

"A total of 55 terror operatives, who are affiliated with different terror groups have been detained. Among those arrested were a number of senior level operatives," a statement said, with public radio saying it included members of Hamas and Islamic Jihad.

The Lebanese army said it dismantled on Thursday another rocket in southern Lebanon after two similar rockets were fired towards Israel the day before but fell short.

The army command said in a communique that following the attack on Wednesday, the military and U.N. peacekeepers heavily patrolled the Marjayoun area where the rockets were launched from and found a new rocket on its launcher.

Defense Minister Ehud Barak warned on Thursday that Israel may resume its attacks on Gaza at any time if a truce that ended a week of bloodshed fails to hold.

The ceasefire "can last nine days, nine weeks or more, but if it does not hold we will know what to do, and then of course we shall consider the possibility of resuming our (military) activity in case of shooting or provocation," he told public radio.

Hamas chief Khaled Meshaal said on Wednesday that Israel had "failed in all its goals" after a Gaza truce deal came into effect, while thanking Egypt's President Mohamed Morsi for his support.

"After eight days, God stayed their hand from the people of Gaza, and they were compelled to submit to the conditions of the resistance," Meshaal said.

Israel and the United States have agreed to work together to prevent the smuggling of weapons from Iran to militant groups in the Gaza Strip, Prime Minister Benjamin Netanyahu said on Wednesday.

"Israel cannot sit idly by as its enemies strengthen themselves with weapons of terror so I agreed with President (Barack) Obama that we will work together -- Israel and the United States -- against the smuggling of weapons to terror organizations, most of which comes from Iran," he said in a televised address.

Hizbullah Secretary-General Sayyed Hassan Nasrallah said on Wednesday that the Palestinian resistance's experience in the most recent conflict with Israel should be studied and evaluated for its “greatness”.

"The U.S., the West, Arabs and Muslims, Lebanese, Palestinians and Gaza should all learn lessons from this experience,” said Nasrallah in a speech he gave on the seventh day of Ashoura, adding that the fighters' performance has reinforced the strength and the power that will lead to “this nation's victory”.
