Iran has strongly rejected the allegations by the US that the country is involved in the training, financing and arming of Iraqi insurgents.

US officials have always been leveling 'baseless and ridiculous' accusations at Iran without providing any proof, Iran's Mehr news agency quoted Foreign Ministry spokesman Mohammad-Ali Hosseini on Monday as saying.

A senior US military commander, Brigadier-General Kevin Bergner, had earlier accused the Quds Force -- a unit of Iran's Revolutionary Guards Corps-- of training groups of 20 to 60 Iraqi insurgents at a time and sending them back to Iraq to fight US troops there.

Bergner claimed that senior Iranian officials were aware of all those activities.

"The Americans try to cover up their four and a half-year failure in Iraq by making such accusations; and instead of accepting the realities, they just insist on their wrongdoings," the spokesman said.

Hosseini said that US troops' attacks on civilians and the country's policies in Iraq would only deepen the Iraqis' hatred towards the occupiers.
