A search operation has been launched after a young boy fell from the Cliffs of Moher in Co Clare.
It is understood the boy became separated from his family on Tuesday.
It is believed they were holidaying in Ireland from overseas.
A search operation was launched when the alarm was raised.
It is understood the crew of the Shannon-based Irish Coast Guard helicopter, Rescue 115, spotted what is believed to be a body in the water at the base of a cliff.
The area was inaccessible at the time with large waves breaking on the shoreline and the search was called off last night.
A spokesperson for the Department of Transport said the Coast Guard is supporting a garda "operation to recover the body of a faller at the Cliffs of Moher".
"The Coast Guard Rescue Coordination Centre in Valentia are assisting along with Doolin Coast Guard Unit and Coast Guard helicopter R115.
"Attempts at recovery have been undertaken using Doolin Coast Guard Unit boat and drone teams, Aran Islands life boat and the Civil Defence drone teams in conjunction with An Garda Síochána," the spokesperson added.
Despite Garda Water Unit members carrying out a comprehensive search of the shoreline yesterday, with help from Coast Guard volunteers on the cliff top and Rescue 115 from above, no trace of a body was found.
Coast Guard rescue crews returned to shore yesterday afternoon as weather conditions were said to be not ideal with low-lying cloud in the area.
A decision on when the search would resume was due to be made when conditions improved.
