A woman and three men were shot dead in a public execution in a Pakistani village after tribal elders found them guilty of adultery, officials said.
The death sentences were ordered by a jirga (council) of elders in the Khyber agency area on the Afghan border.
Sex outside marriage is a crime in Pakistan and tribal village councils often punish those involved with death.
Last year, Pakistan's parliament approved a new bill amending Islamic laws on rape and adultery.
The new law dropped the death penalty for people having sex outside marriage.
"We found a man and a woman in a compromising position along with another man who was drunk and had already committed adultery, and the owner of the house,"
Reports said the executions were watched by some 600 people.
