Polish investigators say the latest evidence about a 1941 massacre of Jews in the eastern village of Jedwabne appears to confirm suggestions that German troops were not involved.

The killing of several hundred people had been blamed on Nazi troops, but evidence has recently come to light indicating that the atrocity may have been carried out by local Poles.

Now an investigation into bullets found at the site has found that they were not of a type used by the Germans at the time.

The investigators say they also have no evidence indicating any significant German presence in the area.

The possibility that Poles were responsible for the killings led to a national debate in Poland on wartime attitudes towards Jews.

President Alexander Kwasniewski apologised earlier this year for the role Poles played in the massacre.
