Muslim extremists in India's Kashmir Valley are again attempting to impose a dress code and other restrictions on women. Police say posters signed by the Lashkar-e-Jabbar extremist group have gone up in colleges in the state capital Srinagar, ordering women to wear the all-enveloping burqa on pain of death. Armed women police officers are guarding girls' schools and colleges. Militants killed four women recently in Rajouri district in the south of the state. One was taken from her home and beheaded. Police in the district said they were killed for not wearing veils, but the director-general of police, A. K. Suri, denied that was the case. In some remote areas, girls have been warned not to go to school after they turn 12. Conservative Muslims believe girls should end their education on reaching puberty. Last year, Lashkar-e-Jabbar tried to impose the same dress code by terrorising women. Several had acid thrown in their faces. Tailors and fabric shops thrived for a while before women went back to dressing normally. Two other militant groups came out against the wear-a-burqa campaign. Militants have tried at various times during the 13-year separatist insurgency in Kashmir to bring society round to their ways. Women wearing tight trousers have been shot in the legs. They once tried to ban the wearing of jeans by men. Owners of video shops and cable television operators have also been attacked. But the impact of such campaigns has invariably been short-lived. The latest campaign has seen the bombing of a bar in Rajouri last week; liquor shop owners are also receiving threats. Police say Lashkar-e-Jabbar is also campaigning against smoking and urging Muslim males to grow beards. Posters quote verses from the Koran advocating beards and go on to warn: 'It is in the interests of all Muslims to follow the Islamic code of conduct.' A new government took power last month promising to bring peace to the war-weary state. The new chief minister, Mufti Mohammed Sayeed, has promised to reconcile Muslim radicals with the rest of society by giving a 'human face' to his government and by alleviating the bitterness of the past. But the new administration has seen an upsurge in militant violence. Mufti Sayeed has said he will not allow militant groups responsible for the recent attacks to sabotage his policy, nor will he show them any leniency. But the Bharatiya Janata Party, the dominant ruling party in New Delhi opposes any policy it perceives as being soft on terrorism, and has criticised the mufti's stand.
