A woman who saw her cousin being killed by falling rocks in Gnejna Bay has issued a plea for the authorities to post warning signs at Delimara and nearby bays where, she said, a similar danger exists.

Carol Ellul said the rocks on the beach at Delimara is concave shaped by erosion. People often shelter below the cliffs and rocks as protection from the sun.

"Thirty-nine years ago I saw my cousin die at Gnejna Bay on his 12th birthday. We went for a day at the beach, a piece of hanging cliff (like the one in Delimara) fell on top of him and on my brother. My brother survived by a miracle. But Gino Portelli died on the way to hospital, I have never forgotten that day, it will stay with me for the rest of my life and I never go near the cliffs of Delimara or anywhere that can collapse. St Peter's Pool has the same structure."

Ms Ellul said the authorities should remove structures which appeared to be in imminent danger of collapse, and also put up warning signs before summer set in.

"It will happen again one day if we do nothing," she warned.
