"On the basis of the information available, there is no evidence that any coalition forces could have been involved in or responsible for this incident," it said in a statement.

The embassy said British diplomats in Tehran were "in close touch" with Iranian authorities over the incident.

On Wednesday, Iran accused the coalition of having fired a rocket which killed an Iranian teenager near the border town of Abadan, state television reported.

The coalition was "responsible for violating Iranian airspace, and for the human and material losses," said a spokesman for the government's Iraq crisis committee, Seyyed Mohammad Sohofi.

Officials said that 13-year-old Hossein Aridi was killed Tuesday on a road near Abadan.

Iranian Foreign Minister Kamal Kharazi has confirmed that two rockets hit the country during the first days of the war, one of which hit a depot at a refinery in Abadan injuring two people.

However, the Iranian press has reported up to two other rocket or missile explosions near the border.
