BAGHDAD, April 10 (IslamOnline.net & News Agencies) - With the fate of three Japanese held in Iraq still unclear, reports from the occupied oil-rich Arab country indicated that more foreigners are either being held by Iraqi militias or are unaccounted for.

Australian television on Saturday, April 10, broadcast a report from Iraq apparently showing a U.S. national held by Iraqi guerrillas following an attack on a U.S. fuel convoy outside the town of besieged town of Fallujah.

Correspondent Peter Cave of the Australian Broadcasting Corporation said his crew had been filming the attack on the convoy Friday, April 9, along the main highway from Baghdad to Fallujah when a car carrying armed fighters drove up.

"They called us over to see their prize -- a hostage, apparently a truck driver," Cave said in the report from Iraq.

The man identified himself in the video report as Thomas Hamill and spoke with a strong American accent.

When asked by Cave what had happened, Hamill said: "They attacked our convoy. That's all I'm going to say."

The man was seated in the backseat of the car between two armed and masked men while two other men were in the front seat.

A military spokesman for the U.S.-led occupation forces earlier said two U.S. soldiers were missing following the attack on the fuel convoy, but he could not confirm they were being held by Iraqi militias.

In a similar development, Germany government officials confirmed Saturday that two members of Germany's crack GSG-9 security police team serving with their mission in Baghdad have gone missing and may be dead.

"Two civil servants working for the German mission in Baghdad have been missing for the past few days," said a German foreign ministry spokeswoman.

"There is no evidence to suggest it is a hostage-taking."

German television reports suggested that the men, aged 25 and 38, had been traveling in a convoy from Jordan to Baghdad, and might have disappeared when they were attacked near Fallujah Wednesday, April 8.

The two were last seen when their diplomatic convoy was pounded by rockets and gunfire while en route from Amman to Baghdad, a Jordanian driver traveling with them said Saturday.

Germany does not have military forces with the U.S.-led occupation force and was one of the staunchest opponent of the U.S.-led invasion of the Arab country.

Meanwhile, Canadian diplomats have made contact with Iraqi militias holding a Canadian aid worker and are negotiating for his release, a report said Saturday.

Fadi Ihsan Fadel, 33, of Syrian origin, was held midnight Thursday by members of a local militia in Kufah, according to his humanitarian organization, the U.S.-based International Rescue Committee.

The Canadian Broadcasting Corporation quoted foreign ministry officials as saying he was in good shape and being fed, and that negotiations were going on for his release.

Canadian efforts to free Fadel are being conducted through the Canadian embassy in the Jordanian capital Amman.

In Tokyo, hundreds of people rallied outside Prime Minister Junichiro Koizumi's office Saturday, demanding the withdrawal of Japanese troops from Iraq to save the lives of three Japanese held there.

"The lives of people are more important than the Japan-U.S. alliance," the demonstrators chanted as they were prevented by police from crossing the street to the prime minister's official residence in the centre of Tokyo.

Ken Takada, who organized the rally, said his group had collected 100,000 signatures to urge Koizumi to yank his troops from Iraq.

Koizumi has vowed to keep his soldiers in the southern Iraqi city of Samawa despite the crisis that overshadowed the arrival of U.S. Vice President Dick Cheney in Tokyo on Saturday for high-level talks.

On Saturday a previously unknown armed group in Iraq said it was holding 30 foreigners and would kill them unless U.S.-led occupation troops pull out of Iraq, reported Al-Arabiya channel.

"We, the Brigades of Martyr Sheikh Yassin, announce that we are holding 30 hostages, including Japanese, Bulgarians, Americans, Israelis, Spanish, Koreans, Italians and" other nationalities, a hooded spokesman for the group claimed in a statement read on the Dubai-based station.

The spokesman, filmed among other group members, all wearing balaclavas, demanded "the departure of American forces and their allies" from Iraq and "the lifting of the siege of the town of Fallujah."

On Thursday, a group calling itself Ansar Al-Din confirmed they were holding two Arabs -- one a naturalized Israeli working for the USAID, the other a Canadian national with a humanitarian group.

A British civilian consultant for a dye works appeared to have been seized in the southern Shiite town of Nasiriyah on Friday, according to the British foreign office.
