The largest hospital in rebel-held east Aleppo was bombed on Saturday for the second time in days as Syrian government forces pressed a Russian-backed offensive to retake the entire city.
Amnesty International said Monday a US-made bomb was used in an air strike on a hospital in Yemen, urging Washington and London to stop supplying the Saudi-led coalition with weapons.
The Saudi-led coalition bombing rebels in Yemen launched an investigation on Tuesday following international condemnation of an air strike that Doctors Without Borders said killed 11 people at a hospital it supports.
Survivors of a US air strike on a hospital in Afghanistan have called for those responsible to go on trial and dismissed an American military investigation that said the bombardment did not amount to a war crime.
At least 16 more people have died of starvation in the besieged Syrian town of Madaya since an aid convoy entered earlier this month, according to Doctors Without Borders (MSF).
