Over 30 children rescued by lifeguards

Lifeguards Adam Pitman and Jon Johnston entered the water with rescue boards and tubes, and brought the individuals safely to shore.

Meanwhile lifeguard, Coral Lewis, who was also on patrol at the time, radioed the coastguard, the spokeswoman said.

Mr Johnston, of Selly Oak, Birmingham, told the BBC's Breakfast programme that the rescue took around 10 minutes overall.

"As we got there, the sandbank faded and shifted , which meant the whole group of 40 people were immediately out of their depth," he said.

"At this time, we had to take our training into practice and immediately went in - myself and another lifeguard - into the water.

"It was more like a relay rescue than anything - trying to get all 40 people back to shore safely. ''

Wales Ambulance Service said two people were taken to Withybush Hospital at Haverfordwest by land ambulance after the incident.
