A mother and her young son have died after being pulled from the sea off Aberdeen beach, police said.

Emergency services launched a rescue operation around 4.40pm on Saturday after reports of five people in difficulty in the water.

An area of the beach was cordoned off while a coastguard lifeboat along with police, fire and ambulance services attended the incident.

Two people were pulled from the water by the coastguard crew while the remaining three were rescued by police officers.

Police later said a six-year-old boy and 37-year-old woman had died as a result of their injuries. STV News understands the deceased were a mother and her son.

A 13-year-old boy, 25 year-old woman and 28 year-old man remain in hospital for treatment.

Chief inspector Stewart Mackie said: "This is a very tragic incident which has resulted in a woman and young boy sadly losing their lives - it will undoubtedly bring shock and sadness to the entire city of Aberdeen and further afield.

"As we work with partners to establish the full circumstances of today's events, we urge anyone who witnessed the incident or perhaps have information that could assist, to make contact with Police via 101.

"Given the recent weather conditions we'd urge members of the public to take care, especially when near coastal or beach areas."

Scotland's First Minister Nicola Sturgeon was among those paying tribute.

She tweeted: "Tragic, heartbreaking news. My thoughts are with all those involved."

Aberdeen Central MSP Kevin Stewart posted: "Sorry to hear of the tragic event that has taken place at Aberdeen beach. My thoughts are with those involved, their families and friends." Police Scotland appealed for witnesses.
