(BBC) Only seven ambulances were free to treat people when the Manchester Arena explosion took place, the public inquiry into the attack has heard.
Dr Edward Tunn, associate medical director for North West Ambulance Service (NWAS), said there was a delay in getting enough crews to the scene.
Seventy-six ambulances were responding elsewhere in Greater Manchester on … “already a busy night,” he said.
Some critically ill casualties waited up to three hours to get to hospital.
