KABUL, Afghanistan — An armed mob that included relatives of a young woman who had eloped with her lover stormed a police station holding the couple in eastern Afghanistan over the weekend, then dragged the lovers off and killed them, officials and witnesses said.

The mob wounded three police officers, one of them seriously, the officials and witnesses said Sunday and Monday in providing accounts of the couple’s violent deaths, often called honor killings.

The woman, Fatiha, 18, was described as having been married against her will and eloping instead with a young man, Hedayatullah, believed to be in his early 20s, from a neighboring village in Wama District of Nuristan Province. But on Saturday the police caught and arrested the couple on suspicion of adultery.

Within hours an armed mob formed at the police station, led by Fatiha’s husband and his family, but also including her brothers and cousins, the officials and witnesses said.
