Saudi bombs destroyed an MSF hospital in Yemen. The article does not tell us whether the attack was an accident.

Over 90% of the people killed by this bombing campaign — and by the other explosive weapons of both sides — are civilians.

Since this bombing campaign is endorsed and supported by the US, the US is indirectly responsible. If the US and Saudi Arabia had not launched this campaign, the Houthis would have won the war in Yemen and there would be less fighting there now — perhaps none.
