An Israeli drone strike killed three cousins, including two children, in the West Bank on Wednesday, according to the local Palestinian governor and a relative, as growing violence threatens to further destabilize the Israeli-occupied territory.

The attack struck the courtyard of the cousins’ home in the town of Tamoun, said Ahmed Asad, the Palestinian governor of the Tubas region.

The Israeli military said it launched a drone strike in Tamoun against a “terrorist cell,” but did not immediately comment on reports in Palestinian media that two children were killed. It later released a statement saying that “due to various reports regarding the results of the strike, the incident is under review.”

Their immediate families could not immediately be reached, but Mamun Abu Muhsin, a member of their extended family, confirmed their deaths.

Wednesday’s aerial bombardment came in the wake of a Palestinian shooting attack two days earlier that killed three Israelis, including two women in their 70s. Israeli officials quickly vowed retribution for the deadly attack.
