London, June 23: A 29-year-old Somali refugee in Britain has been jailed for at least 26 years for stabbing his girlfriend 57 times with shards of a broken mirror. Zakaria Mohamed killed 32-year-old TV recruitment consultant Amina Adan at the home they shared in Walworth, south London. The Old Bailey court heard he had assaulted her twice before during their year-long relationship, but magistrates put off sentencing him so that he could take part in a domestic abuse programme, the Daily Mail reported. The man pleaded guilty to killing his girlfriend in November last year with three knives and shards of glass from a broken mirror. After a row, a drunk Mohamed went home, dragged the woman down the stairs by her hair, beat her unconscious, kicked and stamped on her and stabbed her. When police arrived, he threatened to kill them too and had to be subdued with a Taser gun. The victim, who was brought up in Kenya, was described as being hard working and popular at the Al Jazeera TV news network where she worked in human resources. (IANS)
