Five men have died after a wall collapsed at a recycling plant.
West Midlands Police said all five victims were pronounced dead at the scene of the industrial accident in the Nechells area of Birmingham.
Emergency crews were called to Hawkeswood Metal in Aston Church Road at 8.45am.
A sixth man was taken to hospital with serious leg injuries.
An investigation is under way and the Health and Safety Executive (HSE) has been notified.
West Midlands Fire Service said a large concrete structure containing metal had collapsed at the site.
Two ambulances, an air ambulance, a hazardous area response team and an emergency planning officer were sent to the scene.
A West Midlands Ambulance Service spokesman said: "On arrival, ambulance crews found a wall that had collapsed.
"Sadly, there was nothing that could be done to save the five men who had been working next to it.
"A sixth man was partially trapped by the falling concrete, but had managed to get out from the rubble himself.
"He was treated at the scene by ambulance staff and the doctor from the air ambulance for a broken leg before he was taken to Heartlands Hospital for further treatment."
West Midlands Fire Service deployed its Technical Rescue Unit (TRU) to the scene equipped with heavy lifting and cutting equipment.
Assistant chief fire officer Gary Taylor said: "This is a devastating incident for everyone involved. Our thoughts and deepest sympathies are with the victims' families and colleagues."
