In a post on Twitter, Amnesty International condemned Israel for hitting its headquarters with a rocket.
"We strongly condemn attack on the Palestinian Independent Commission for Human Rights whose office in Gaza was struck by an Israeli missile earlier this morning. Strikes targeting civilian buildings is a violation of international law."
When confronted with evidence that it was in fact an Islamic Jihad rocket that struck the building, Amnesty refused to retract its statement and instead called for an investigation.
"Conflicting information is circulating about what exactly hit the Palestinian Independent Commission for Human Rights office in Gaza and where the attack came from. Amnesty International is calling for an impartial investigation into this incident and other events in Gaza today," they wrote.
