"We strongly reject and will resist with weapons any military intervention under the umbrella of the United Nations, the Security Council, NATO, or Islamic and Arab countries," a group calling itself the Iraq Liberation Army said in a statement shown on the Dubai-based al-Arabiya television.

Thirty-two US soldiers have been killed in guerrilla attacks in Iraq since President Bush declared major combat over on May 1.

Troops from Spain, Poland, Ukraine, Bulgaria, Hungary, Romania, Slovakia, the Baltic states and possibly from the Philippines, Thailand, Mongolia and Fiji are likely to be part of the peacekeeping forces in Iraq.

Bangladesh and Pakistan, both Muslim nations, have also been asked to take part in peacekeeping operations but they have not announced any decision yet and there is considerable domestic opposition to the proposals.

India said on Monday it would not send troops to Iraq without a United Nations mandate, rejecting a request from Washington for help in the war-torn nation.

Qatar-based al-Jazeera television also showed a statement from another Iraqi group -- the "Iraqi National Islamic Resistance: 1920 Revolution Brigades," in reference to Iraq's history fighting British colonial rule -- warning against further foreign intervention.

"It implored Arab and Islamic countries about the seriousness of sending their troops to Iraq," al-Jazeera quoted the statement as saying.

It said that anti-US attacks had forced Washington to seek help from multinational forces and speed up the creation of a Governing Council, which was launched on Sunday.

A group claiming to be an Iraqi branch of Osama bin Laden's al-Qaeda network claimed responsibility for attacks on US soldiers in an audio tape broadcast on al-Arabiya on Sunday but its rhetoric sounded more typical of Saddam supporters than Islamic militants.

Analysts say there is no shortage of groups with animosity for the Americans, from Baathists, to Arab Sunni, Shiite and Kurdish Islamists, to ordinary people seeking revenge for US treatment of Iraqis, which is seen as heavy-handed.

Meanwhile a previously unknown group, calling itself the Iraqi Jihad Movement, said it would wage attacks against US forces in Iraq, in a statement received here by AFP.

It also paid tribute to Syrians who came to fight the US forces in the three-week war that ousted Iraqi leader Saddam Hussein in April.

It was the second statement from an unknown Islamist group vowing to attack US soldiers in two days.

On Sunday, a terrorist group claiming links to the al-Qaeda network announced it had carried out attacks on US troops in Iraq and threatened further violence in a taped message broadcast by the Al-Arabiya television station.

The hitherto-unknown Armed Islamic Movement warned it would continue to target American troops and promised to "break their backs".

Earlier, a grenade blew up Monday outside coalition headquarters in central Baghdad, in a bold assault on the symbol of US power in Iraq, two days ahead of the anniversary of Saddam Hussein becoming president.

A car drove up at around 4:40 pm (1240 GMT) and an assailant hurled the grenade, which landed under a black GMC jeep, before speeding away, said Iraqi police captain Mohammed Muauyez, without reporting casualties.
