The Israeli military has said one of its aircraft hit an ambulance in Gaza on Friday.
Earlier, Gaza's Hamas-run health ministry said an Israeli strike hit a convoy of ambulances near the Al-Shifa hospital, the territory's largest hospital.
In a statement, the ministry's spokesman said "a convoy of ambulances which was transporting the wounded" was hit as it was leaving the hospital in Gaza City towards Rafah in the south.
It said the blast killed multiple people. The Israeli military spokesperson claimed the ambulance hit was being used by Hamas militants. This claim could not be independently verified.
The World Health Organization has said the Al-Shifa hospital currently faces severe overcrowding, with a bed occupancy rate of 164%.
