Five people including a teenage couple who married against their families' will have been killed by relatives in the latest incident of so-called honour killing in Pakistan, police say....

The couple - Kamalan and Allah Rakhio - both 18 and from rival clans in the southern province of Sindh, had married about three months ago after eloping, said Usman Subaho, a police officer investigating the case.

"They were killed just a few days after returning to their village after getting married in Karachi," he said....

The girl's family took her wedding as a slight on their honour.

The attackers stormed the couple's house, killing them and three other family members including a three-year-old girl, said Subaho.

Eleven family members were wounded in the attack, he said.

The Human Rights Commission of Pakistan says about 1,000 people are killed in honour-related crimes every year in Pakistan.
