Three Japanese hostages were freed yesterday, but the murders of an Iranian diplomat and an Italian captive sent chilling proof of the risks foreigners face in Iraq, where rebels are battling the US-led occupation.
Al Jazeera television showed the three Japanese, apparently in good health, after they had been handed over to the Muslim Clerics Association, a Sunni Muslim body, in Baghdad.
"I'm very happy they have been released," said a senior member of the association, Abdul Salam al-Kubaysi. "I call on them to visit Fallujah again to see for themselves the havoc wreaked on the city by US warplanes and cluster bombs."
Fallujah has seen fierce fighting this month between US Marines and Sunni insurgents. Hospital officials said more than 600 people have been killed in the city west of Baghdad.
Japan has endured a week of anguish since the kidnappers threatened to kill the three hostages unless Tokyo withdrew its troops from Iraq. Japan rejected the demand.
Italy has also vowed to keep its troops in Iraq despite the murder of one of four Italian hostages held there.
"They have destroyed a life. They have not cracked our values and our efforts for peace," Italian Prime Minister Silvio Berlusconi said after the killing of Fabrizio Quattrocchi.
The freed hostages are Noriaki Imai, 18, who wanted to research the effects of depleted uranium weapons, journalist Soichiro Koriyama, 32, and aid worker Nahoko Takato, 34.
Japanese authorities were trying to confirm reports that two more Japanese civilians had been kidnapped near Baghdad.
Underscoring the lawlessness sweeping Iraq, an Iranian diplomat was killed near the Iranian mission in Baghdad. Iran state television named him as first secretary Khalil Naimi.
A Reuters correspondent saw a car with at least two bullet holes in it. A body was slumped in the vehicle, which had smashed into a lamp-post.
"We have been told that he was driving his car to go to the embassy and three men drove up and shot him," an Iranian official said in Baghdad.
An Iranian delegation has been in Iraq to help mediate between US-led authorities and Shiite cleric Moqtada al-Sadr.
US troops are poised around the Shiite holy city of Najaf, where Sadr is holed up. The US has vowed to kill or capture the rebel cleric and destroy his militia.
In Fallujah, residents said US planes struck targets in several districts amid overnight clashes between rebels and US Marines. There was no word on casualties.
Fighting calmed after daybreak, though Marine tanks opened fire after a rebel attack outside the town, witnesses said, and four insurgents were killed 16km to the north.
Al Jazeera television received a videotape of the Italian private security guard's murder, which it said was too bloody to screen.
The killing of the Italian by a previously unheard-of Iraqi group followed a kidnap spree that has snared foreigners from a dozen countries this month, the bloodiest since former Iraqi president Saddam Hussein was ousted a year ago.
It was the first such publicized killing.
Kidnappers freed French journalist Alexandre Jourdanov on Wednesday, but more than a dozen foreigners remain captive.
Al Jazeera said their captors had threatened to kill three other Italian hostages, colleagues of Quattrocchi in a US security firm, if Italian troops were not withdrawn immediately.
