"Iraqi citizens voluntarily turned in a variety of weapons under the Weapons Turn-In Program that began June 1," a coalition statement said.

"As of today, Iraqi citizens have delivered to Weapons Collection Points a total of 123 pistols, 76 semi-automatic rifles or shotguns, 435 automatic rifles, 46 machine-guns, 162 anti-tank weapons, 11 anti-air weapons, and 381 grenades and other explosive devices."

However, some five million weapons are believed to be in circulation in Iraq where lawlessness has taken root since the April 9 ouster of Saddam Hussein's regime.

Possession of heavy and automatic weapons now carries a one-year jail term and a 1,000-dollar fine.

The coalition arms controls which came into force on June 15 after a two-week amnesty period allow private individuals to keep light weapons in their homes and businesses.

But separately it requires all Iraqi factions to disarm their militias, outside the three northern provinces still held by two Kurdish former rebel groups which fought alongside the coalition during the war.

Meanwhile, the US army's ongoing bid to mop up resistance in northern Iraq has left at least 113 dead this week, according to US and Iraqi sources, as a top Iraqi politician warned that attacks would continue until local people are given more power.

US forces killed 82 combatants at a desert training camp at Sahl, near the border with Syria, a Muslim leader from a neighbouring village told AFP.

Some of the fighters appeared to have been summarily executed, said Sheikh Gharbi Abdul Aziz, imam of the main mosque at Rawa, a few kilometres (miles) from Sahl.

Rawa villagers who went to the camp found the corpses of seven people who had been handcuffed and shot in the forehead, chest or in the back of the head, the imam said.

He said the villagers had found another 50 bodies all in a line at the camp, which appears to have been used as a training ground by die-hard supporters of ousted leader Saddam Hussein, ousted by US-led coalition forces in April.

He said he helped bury 82 bodies after fighting erupted Thursday at dawn at the suspected extremist training camp.

The US military had reported killing 27 Iraqis after clashes broke out late Thursday, when a US 4th Infantry Division armoured patrol came under rocket propelled grenade attack near Balad, about 80 kilometres (50 miles) northeast of Baghdad.
