The girls, named Samreen, 19, and Sanam, 17, were critically injured in the attack which was carried out by a man only identified as Sajid. Both girls were asleep on the roof of the single-storey family home at Koohi Goth in Landhi on Tuesday when the attack happened.

The pair were rushed to the Jinnah Postgraduate Medical Centre for treatment and doctors have since said they are both now out of danger. The man, a relative of the family, had previously asked the girls to marry him, but was rejected, according to the girls' father Qadir Buksh. Mr Buksh told police: “Sajid has been interested in getting married with one of my daughters, which we already refused.”

The father also stated it was not the first time the man had threatened the life of the family. A police official said: “Sajid is a member of a gang and also a drug addict.” Authorities have registered a First Information Report, the first step in the criminal system, against Sajid and an investigation is underway, according to Shah Latif SHO Ikhlaq Ahmed.

No one has been arrested as of yet. Pakistan recently passed anti-honour killing and anti-rape bills in October 2016 which changed the country’s 1860 Penal Code, although the draconian anti-women laws have never been fully repealed and violent acts against women still occur. The actress and model Qandeel Baloch (aka Fouzia Akeem) was killed last year by her brother who later confessed to her murder after he said she had bought “dishonour” to the family.

In June 2016 Muqaddas Bibi, who was seven months pregnant, had her throat slit by her parents and brother after choosing to wed a man she loved rather than submit to an arranged marriage. In the same month, 16-year-old Zeenat Rafiq was burnt to death by her mother in Lahore for marrying without family consent, in a case that sparked widespread disgust throughout the country.
