According to the article, nobody actually knows when the attack took place. And the BBC is assuming that it was an Israel attack, even though 1/3 to 1/6 of Hamas rockets fall back into Gaza - that is disingenuous. Furthermore, the single photograph of the clinic shows absolutely zero kinetic damage. How does an Israeli shell or bomb leave no kinetic damage? The Hamas rockets leave little to no kinetic damage as they are fuel-air bombs, not HE.
