LAHORE, Pakistan — A young Pakistani couple were tied up and killed, their throats slit with a scythe, after they married for love, the police in Pakistan said Saturday.

The couple, a 17-year-old girl and a 31-year-old man, married on June 18 without the consent of their families in Satrah, a village in Punjab Province in eastern Pakistan, the police said.

The girl’s mother and father lured the couple home on Thursday with the promise that their marriage would receive the family’s blessing, Rana Zashid, a local police official, said.

“When the couple reached there, they tied them with ropes,” Mr. Zashid said. The girl’s father then “cut their throats,” he said.
