KABUL, Afghanistan  The Taliban on Sunday ordered their first public executions by stoning since their fall from power nine years ago, killing a young couple who had eloped, according to Afghan officials and a witness.

The punishment was carried out by hundreds of the victims’ neighbors in a village in northern Kunduz Province, according to Nadir Khan, 40, a local farmer and Taliban sympathizer, who was interviewed by telephone. Even family members were involved, both in the stoning and in tricking the couple into returning after they had fled.

Mr. Khan said that as a Taliban mullah prepared to read the judgment of a religious court, the lovers, a 25-year-old man named Khayyam and a 19-year-old woman named Siddiqa, defiantly confessed in public to their relationship. “They said, ‘We love each other no matter what happens,’ ” Mr. Khan said.

The executions were the latest in a series of cases where the Taliban have imposed their harsh version of Shariah law for social crimes, reminiscent of their behavior during their decade of ruling the country. In recent years, Taliban officials have sought to play down their bloody punishments of the past, as they concentrated on building up popular support.
