LONDON (AFP) - Britain has launched a formal investigation into a reported friendly fire incident in which two Danish soldiers died in southern Afghanistan, the Ministry of Defence said Monday.

Danish television reported on Sunday that the Danish troops, who died on September 26, were killed by missiles fired by British forces who mistook them for Taliban fighters.
""We are working closely with the Danish government to establish the details and the causes of this incident and there is a Board of Inquiry into it ongoing,"" said an MoD spokesman.
""It would not be appropriate to comment further before the Board of Inquiry is complete,"" he added.
According to the Danish TV2 television station Sunday, British troops from the International Security Assistance Force believed they were fighting Taliban when they launched six to eight missiles at a position held by 14 Danish soldiers.
The British forces kept firing for nearly an hour without noticing that it was another ISAF position, killing Danish soldiers Thorbjoern Ole Reese, 22, and Mikkel Keil Soerensen, the TV station's correspondent said.
Two Danish soldiers said they knew they had been fired on by the British because they found remains of British missiles in their position, on one side of the Helmand river in the Upper Geresk Valley.
The two soldiers' deaths brought to six the number of Danish troops killed in Afghanistan. Denmark currently has 550 soldiers in the country, mostly in Helmand province under British command.
The MoD spokesman declined to forecast when the British investigation into the incident would conclude.
""Every time we have a serious incident we launch one of these boards of inquiry. It looks at the individual circumstances of the incident,"" he told AFP.
""If it's a complicated matter it will take longer than if it's a straightforward matter.""
There have been several incidents of friendly fire in the international effort against the Taliban, which involves troops from nearly 40 countries and which was launched after the invasion of Afghanistan after the September 11, 2001 attacks in the United States.
