Two laboratories in the university, which served as research and development centers for Hamas's military wing, were targeted. The development of explosives was done under the auspices of university professors.

University buildings were also used for meetings of senior Hamas officials.

 The IDF said rockets and explosives were stored in the buildings.

And as for the usual whinings that Israel is now using "disproportionate force" coming from France and others, what is proper force?  And who is to decide?  Are the Israelis just passive victims, letting others set the limits of what they must endure?  Do others have the right to write the rules, excluding Israel? If Israel breaks these artificially imposed terms are they aggressors? Actually these questions aren't worth answering; those who gurgle about Israel's disproportionalty reveal their own bigotry.
