At work, have not had time to read it properly, but found this via an excited "Iron Age house burnt by Hannibal" story on CNN. The study itself makes no mention of said Mr Barca, but hey, the authors got themselves a CNN headline ;D

Nice bit of archaeological science that. What I did like was the authors don't speculate on why the building burned down or who might have been responsible. I presume a press release did, however, and that got the CNN coverage.
The oddity is that if the house burned because of hostile activity, they were arguably pretty incompetent or careless attackers if they left a horse and five sheep/goats to die rather than looting valuable livestock.
