The battle lasted several hours

Mr Nunu said: “Anyone who belongs to this group has to immediately hand himself and his weapons over to the Palestinian police and security forces.”

Another Hamas official, Sami Abu Zuhri, branded the cleric’s speech “wrong thinking”.

Sealed off

Hamas fighters on Friday fired rocket-propelled grenades at Ibn-Taymiyah mosque, where at least 100 Jund Ansar Allah supporters were holed up.

These declarations [of an Islamic emirate] are aimed towards incitement against the Gaza Strip

The entire neighbourhood was sealed off as the shooting continued after dark – in what was one of the most violent incidents in the Hamas-controlled Gaza Strip since an Israeli offensive in December and January.

Abdul-Latif Moussa and his armed supporters had sworn to fight to the death rather than hand over authority of the mosque to Hamas.

During his own Friday sermon, the leader of Hamas in Gaza, Ismail Haniya, dismissed Mr Moussa’s comments.

“These declarations [of an Islamic emirate] are aimed towards incitement against the Gaza Strip and an attempt at recruiting an international alliance against the Gaza Strip.

“And we warn those who are behind these Israeli Zionist declarations: the Gaza Strip only contains its people.”

Israel must investigate the “unlawful” killing of 11 civilians carrying white flags during its Gaza operation earlier in 2009, Human Rights Watch has said.

Five women and four children were among those killed in seven incidents detailed by the US-based rights group.

Researchers said the soldiers at best failed to protect civilians, and at worst deliberately shot at them.

Israel has launched investigations into five “white flag” incidents, but says Hamas exploited civilians with flags.

In one incident, east of Jabalya, HRW said Israeli soldiers fired at two women and three children, three of whom were holding pieces of white cloth.

Two girls, aged two and seven were killed, and another, now aged four, was left paralysed below the waist.

The five were standing outside their home after an Israeli soldier had ordered them to leave it, HRW said.

“We spent seven to nine minutes waving the flags, and our faces were looking at them [the soldiers],” HRW quoted the girls’ grandmother as saying.

“And suddenly they opened fire and the girls fell to the ground.”

Two of the incidents in question have also been investigated by the BBC.

In five of the seven incidents, Israeli soldiers shot at civilians who were walking down the street with white flags, trying to leave the areas of fighting, HRW said.

“All available evidence indicates that Israeli forces were in control of the areas in question, no fighting was taking place there at the time, and no Palestinian forces were hiding among the civilians or using them as human shields,” the report said.

The Israeli foreign ministry has opened investigations into at least five cases involving Palestinians who were waving white flags.

As of the end of July, one case had been closed. The Israeli military said troops had fired at “suspicious men” who ignored warnings as they walked near a Palestinian family carrying a white flag.

Sadly, Hamas terror operatives ruthlessly pervert the intent of the IDF’s obligations to prevent harm to civilians by exploiting those with white flags as cover for belligerent action and to protect themselves from return fire

Statement by Israeli military

Israelis ‘followed law in Gaza’
HRW said its findings were based on site investigations, ballistic evidence found at the scene, medical records of victims and lengthy interviews with multiple witnesses.

An Israeli government spokesman said the report lacked credibility because it was based on evidence from an area under Hamas control.

The Israeli military said troops were obliged to respect white flags, but accused “Hamas terror operatives” of “exploiting those with white flags as cover for belligerent action and to protect themselves from return fire”.

But it gave no details of specific incidents.

Israel has said its soldiers acted lawfully during the operation, although some mistakes were made, such as the bombing of a house containing 21 civilians by accident.

It says it went to great lengths to distinguish between civilians and combatants, while Hamas put civilians at great risk by firing rockets from near schools and UN facilities, commandeering hospital facilities and ambulances, hiding weapons in mosques and booby trapping civilian neighbourhoods.

War crime accusation

Human Rights Watch last week accused Hamas of war crimes, for firing rockets at Israeli population centres.

The group also says Palestinian militants operated from populated areas.

HRW’s Bill Van Esveld said last Thursday that a Newsweek report quoted in a recent Israeli Foreign Ministry briefing was “as clear evidence of human shielding [by Hamas] as you’re going to get”.

Journalist Rod Nordland wrote on 20 January: “Suddenly there was a terrific whoosh, louder even than a bomb explosion. It was another of Hamas’ homemade Qassam rockets being launched into Israel – and the mobile launch-pad was smack in the middle of the four [apartment] buildings, where every apartment was full.”

But Mr Van Esveld said he was only aware of evidence of “three or four” such cases, and had seen more evidence of the use of human shields by Israeli troops than by Palestinian militants.

The Israeli activist group Breaking the Silence has published anonymous testimonies of Israeli soldiers describing a procedure in which they said Palestinians were forced at gunpoint to enter building where militants were hiding.
