Mohammed Shriteh, 30, is an ambulance driver registered with and trained by the Palestinian Red Crescent Society.
His first day of work in the al-Quds neighbourhood was January 1, the sixth day of the war. "Mostly the war was not as fast or as chaotic as I expected," Mr Shriteh told the Herald. "We would co-ordinate with the Israelis before we pick up patients, because they have all our names, and our IDs, so they would not shoot at us."
Mr Shriteh said the more immediate threat was from Hamas, who would lure the ambulances into the heart of a battle to transport fighters to safety.
"After the first week, at night time, there was a call for a house in Jabaliya. I got to the house and there was lots of shooting and explosions all around," he said.
Because of the urgency of the call, Mr Shriteh said there was no time to arrange his movements with the IDF.
"I knew the Israelis were watching me because I could see the red laser beam in the ambulance and on me, on my body," he said.
Getting out of the ambulance and entering the house, he saw there were three Hamas fighters taking cover inside. One half of the building had already been destroyed.
"They were very scared, and very nervous … They dropped their weapons and ordered me to get them out, to put them in the ambulance and take them away. I refused, because if the IDF sees me doing this I am finished, I cannot pick up any more wounded people.
"And then one of the fighters picked up a gun and held it to my head, to force me. I still refused, and then they allowed me to leave."
Mr Shriteh says Hamas made several attempts to hijack the al-Quds Hospital's fleet of ambulances during the war.
"You hear when they are coming. People ring to tell you. So we had to get in all the ambulances and make the illusion of an emergency and only come back when they had gone."
Eyad al-Bayary, 32, lost his job as a senior nurse at the Shifa Hospital, the largest in Gaza City, about six months ago because he is closely identified with Fatah, the rival political movement of Palestinian Authority President Mahmoud Abbas.
Twice last year Mr Bayary was arrested by Hamas, and once he was jailed for six days for flying the Fatah flag above his house in Jabaliya. He now works part-time as an English teacher at al-Azhar University.
"After the first day of the war, I go to the hospital to work, to help, but I was told to go away. They tell me 'you are not needed here' and they push me away," Mr Bayary said.
Since the ceasefire was declared on January 17, Hamas has begun to systematically take revenge on anyone believed to have collaborated with Israel before the war.
Israel makes no secret of the fact that it has a network of informants inside Gaza who regularly provide information on where Hamas leaders live, where weapons are being stored and other details that formed an important part of Israel's battle plan.
According to rumour, a number of alleged collaborators have already been executed. Taher al-Nono, the Hamas government's spokesman in Gaza, told the Herald that 175 people had been arrested so far on suspicion of collaborating.
"They will be dealt with by the court and the judge and we will respect the judge's decision," Mr Nono said.
And if the sentence is death?
"We will respect the decision."
But the breakdown between Hamas and Fatah over the last 18 months did not prevent some co-operation between the two sides during the war.
The commander of one al-Aqsa Martyrs Brigade unit - the brigades are a coalition of secular militia groups which operate under the loose umbrella of Fatah - said the real enemy remains Israel.
The unit commander, who used the name Abu Ibrahim, invited the Herald into his home.
On the wall of his lounge room hung the portraits of George Habash, who founded the Popular Front for the Liberation of Palestine, a communist paramilitary organisation, and Abu Ali Mustafa, the man who succeeded Habash as leader of the PFLP and who was killed by Israeli forces in 2001.
"Of course we fought together with Hamas because we all have the same aim: to liberate our homeland," he said.
With his two-year old daughter on his knee, Mr Ibrahim, 30, said he would never accept peace or negotiation, even if it might lead to the creation of a Palestinian state.
"I believe in the existence of Israel because it exists on my land - but the war with Israel will only end when I liberate all of my land. This last war with Israel was not the first war, and it will not be the last."
Rebuilding the Strip
GAZA CITY: Hamas will begin a big reconstruction effort in the Gaza Strip today as the territory's 1.5 million people start to recover from the devastating three-week war with Israel that claimed more than 1300 lives and destroyed thousands of buildings, factories and farms.
Life was beginning to return to a relative state of normality yesterday, with schools, universities and businesses back open.
But with most government buildings destroyed during the war, and piles of concrete rubble on street corners, Gazans face a huge effort to return the Strip to the impoverished state that existed before the war began.
Thousands of Gazans who lost their homes are still living in temporary accommodation provided in United Nations Relief and Works Agency schools, and electricity is being rationed, with homes receiving power for just a few hours a day.
A Hamas spokesman in Gaza, Ayman Taha, said his organisation would observe a truce with Israel for 18 months on the condition all the crossing points with Israel were opened.
With Hamas's popularity apparently plummeting in as a result of the war, the movement's leadership is using financial handouts to boost morale.
Hamas leaders from Gaza and Damascus, Syria, travelled to Cairo yesterday to meet Egyptian intelligence leaders and leaders of the Palestine Liberation Organisation for talks aimed at resolving Hamas's dispute with the Fatah movement of the Palestinian President Mahmoud Abbas.
In Israel the appointment of George Mitchell as special envoy of the US President, Barack Obama, to the Middle East has met with caution and suspicion.
Israeli Foreign Ministry officials were scrambling to put together a brief for Mr Mitchell, who is due to visit Jerusalem and the West Bank city of Ramallah this week, as well as Egypt and Jordan.
Israeli officials believe Mr Mitchell's first step will be to recommend the "road map for peace" plan announced by the former president George Bush in 2002 be extended.
Israelis have also begun to turn their attention to the general elections on February 10. With polls indicating the right-wing Likud party leader Benjamin Netanyahu is on track to return to the Prime Minister's office he occupied in 1996, the centrist Kadima Party leader, Tzipi Livni, warned yesterday that if the far-right won government it would lead to an inevitable rift with the US.
