Three Britons - all members of the same family - have been shot dead in a marriage dispute in eastern Pakistan, local police have said.
Mohammad Yousaf, 51, his wife Pervez, 49, and daughter Tanya, 23, were killed at a cemetery in a village near Gujrat.
The three, of Nelson, Lancashire, were shot by four gunmen - understood to be related to them - after an argument broke out.
One man has been arrested and two other suspects are on the run.
Eyewitness Muhammed Anwar described how two groups of attackers had been waiting for the family - inside and outside the cemetery.
Mr Anwar, a relative of those killed, said the family had just arrived and started praying at a grave when they were attacked and shot at.
He said the family had been warned to stay away from the village, because of the tension surrounding marital difficulties between Mr Yousaf's son and a girl, believed to be his cousin, from the village, but nobody had expected such a reaction.
BBC Islamabad correspondent Aleem Maqbool said two of the suspects were believed to be nephews of the murdered couple - who were in Pakistan to attend a wedding.
Police in Pakistan have said the murders were a result of a long-running dispute and, according to our correspondent, are not looking for anybody outside of the family.
Mr Yousaf's son and his wife are reported to have had a "messy divorce".
Tariq Abbas Qureshi, Gujrat police chief, said the killings were premeditated and carried out by heavily armed attackers.
The police chief said one of the suspected attackers was in custody and another was killed at the scene due to what appeared to be friendly fire.
Two others are currently on the run.
Family friend Mohammed Iqbal, who sits on Pendle Borough Council and Lancashire County Council, said: "They went for a wedding and a holiday and they are now having to bury members of their family."
The BBC's Orla Guerin said there were 215 killings in Gujrat last year, most of which are thought to have been related to so-called honour.
