The US and Russia are trading accusations over the bombing of hospitals in rebel-held areas of Syria as diplomatic efforts to secure a ceasefire falter.
A Pentagon spokesperson accused Russia and Syrian government forces of destroying two major hospitals in the divided city of Aleppo on Wednesday, without specifying when the air strikes took place.
But Igor Konashenkov, from Russia’s defence ministry hit back by claiming Moscow tracked two US Air Force A-10 jets bombing Aleppo on the day.
American officials denied hitting a Doctors Without Borders (MSF) hospital in the southern town of Tafas in strikes that killed three people on Friday.
