A US drone attacked and destroyed a house in Pakistan’s Kurram tribal agency on Monday evening, leveling the building and killing all within. At least 20 people were reported slain, all termed “militant suspects,” but none identified.

No one seems to know the identities of any of the slain, and as is keeping with US strikes in Pakistan, US officials have not offered any details on why they attacked the site, or even conceded that they’d done so.

Pakistani officials were quick to sign off on the US strike killed “extremists,” however, and marveled at the high death toll, saying 20 killed proved that the house must’ve been a “main center” for militants in the area.

In reality, it’s not clear the US even knew that many people were in the house. Pakistan certainly didn’t, reporting five slain initially before 15 more people were found buried under the rubble, and posthumously declaring them all militants as well.
