"We ask people to please stay away from this particular area while the emergency services are at work.
"We would remind people to be mindful when out walking on the coast. Standing on cliff edges and at the base of a cliff are dangerous places to be as it is impossible to predict when the next piece might fall or how big it will be."
A Suffolk Fire and Rescue Service spokeswoman said: 'We received a call at around 1pm to say a man was trapped at the cliffs.
"A man and his dog were partially trapped by a section of the cliff face.
"Five fire engines went to the scene, who along with coastguard, RNLI, members of the public and police all helped out."
A spokeswoman for Suffolk police said: "Despite the efforts of those at the scene, the man was located but had sadly died."
