Kinda. War tactics have changed since then. Back in the day we had sieges to starve the population out of fortified citiesin order to capture them. That was a fair enough and totally expected way to wage war back then. In order to take a city you probably still have to expect tokill civilians there. It's too bad really, but war isn't clean.
Isolated bombings targetting people could be considered terrorism. Suicide bombings are terrorism. Razing a city to the ground in a war scenario isn't. In my opinion.
