A couple were shot dead in an apparent honour killing after they refused to let their two daughters marry their nephews, a friend said.
Gul Wazir and his wife Niaz Begum were eating breakfast when three men burst in and carried out the "revenge" attack.
A row erupted when the taxi driver was asked by his Pakistan-based brother Noor if he would allow his daughters to marry his sons Awal Zamir and Rehman.
But the daughters - who had stayed at home in Alum Rock, Birmingham - refused the proposals.
Mr Wazir was visiting relatives in Salehana, a remote village in Nowshera province, with his wife and 28-year-old son Mehboob Alam, when the approach was made.
Family friend Hassan Ahmed said Mr Wazir refused the offer because his daughters were worried about the language barrier and cultural differences.
As a result, a meeting of four village elders was called and they agreed with the Briton and his wife.
Mr Wazir thought the matter was closed but on Friday three men sprayed bullets at the couple as they chatted over breakfast, Mr Ahmed said.
Their son only escaped because he was upstairs taking a shower. Hearing the gunfire he rushed downstairs to find a bloodbath and his parents dead.
Mr Ahmed added: "This was a revenge killing. Everybody has arms on them in this particular area. It's terrible."
