Iran Wednesday rejected Britain's claims on Tehran's involvement in attacks to British soldiers in southern Iraq and weapon smuggling to that country, terming it as a "lie".

Earlier in the day, Britain accused Iran's Revolutionary Guard of supplying explosives technology to insurgents in Iraq who have killed several British soldiers in a wave of attacks this year.

In a swift response, Iranian Foreign Ministry spokesman Hamid- Reza Asefi said, "Britain's conspiracies have been revealed and its scandal in Iraq has made London make up this lie."

London also claimed there is evidence that Iran was in contact with Sunni Muslim rebel groups fighting foreign forces in Iraq.

Asefi asked the British side to present their documents if they have any, asserting that "for sure there is no document because the British themselves are the cause of continuation of insecurity and instability in Iraq and a source of crisis in that country and are trying to blame others for what they do."

The spokesman stressed that Iran's policy toward Iraq is positive and all Iraqi officials have admitted Iran's constructive role there.
