More than 2,800 so-called honour attacks -- punishments for bringing shame on the family -- were recorded by Britain's police last year, according to figures released on Saturday.
At least 2,823 incidents of "honour-based" violence took place, with the highest number recorded in London, the Iranian and Kurdish Women's Rights Organisation (IKWRO) found.
The figures were compiled from 39 out of the 52 British police forces. The others were unwilling or unable to provide data. Eight areas recorded at least 100 incidents, the figures showed.
The attacks included murder, mutilation, beatings, abduction and acid attacks.
Compared with 2009 figures released by 12 police forces, there was a 47 percent rise in incidents.
