The Kremlin has accused Germany of covering up an alleged rape of a Russian 13-year-old girl by 'Arabic looking men' for 'the sake of domestic politics'.

A teenager identified only as Lisa - the child of Russian immigrants in Berlin, Germany - was allegedly attacked in the city earlier this month.

The incident was then turned into a diplomatic row by Russia, which accused Germany of 'covering up reality in a politically correct manner for the sake of domestic politics.

Russian Foreign Minister Sergei Lavrov accused Germany of 'covering up reality' amid allegations a Russian 13-year-old girl was raped by 'Arabic looking men'

Russian Foreign Minister Sergei Lavrov said : 'I hope there will be no repeat of cases like that with our Lisa. It's completely clear that she didn't disappear voluntarily for 30 hours.'

Lavrov claimed that Lisa was abducted and raped repeatedly over a 30-hour period. But Berlin police furiously deny this version of events and the matter is still being investigated.

They say that she did go missing - but that any sexual contact she had seems to have been consensual.

'We cannot say more out of respect for the girl and her family and the privacy of all,' said a spokesman.

Berlin prosecutors are investigating the incident. But the incident has strained relations with Russian immigrants in Germany.

Over the weekend thousands protested in various towns, including 700 in Berlin who turned up to a demonstration outside Chancellor Angela Merkel's office.

The crowd held banners reading: 'We're against the refugees' and 'Lisa we're with you.'

Lisa's aunt told a Russian TV channel that 'an Arabic looking man' kidnapped her on January 11.
