incendiary

We saw photographs of bodies riddled with pellets from fragmentation bombs or charred by incendiary weapons (besides napalm, the Americans also drop white phosphorus, Thermit, and magnesium on the Vietnamese).

Earlier that year Italian Jews had come under serious attack when an incendiary publication, Gli ebrei in Italia (The Jews in Italy), had flooded the bookshops. The author, Paolo Orano, was a Fascist publicist whose book helped to harden Italian public sensibility against the Jews and pave the way for their eventual persecution.

Politics is an incendiary topic; it tends to cause fights to break out.
