The Palestinians on Sunday released unusual footage showing armed fighters in the Balata refugee camp in Nablus disembarking from a vehicle disguised as an ambulance. According to Palestinian reports, the video was filmed approximately two and a half weeks ago during an IDF raid on the camp.
On the day of the operation, Palestinians reported the deaths of two individuals, including an 80-year-old woman.
Palestinian sources explained the delayed release of the footage, saying it had been held by a local shopkeeper in Balata and only surfaced now.

Article 12 (from the 1993 adoption) of the additional protocols from 1974-1977:
As I read it, it seems very clear it would contravene section 4 there.
EDIT: Actually I’d not call it clear. Because it seems to me they’re talking more about using hospitals and the like to shield military units. But I would argue hiding a unit in an ambulance is a good interpretation too.
