A teenager and a young boy have drowned in separate incidents in Cavan and Dublin.
A 16-year-old boy died after he got into difficulty while swimming in a lake in Co Cavan this afternoon.
The incident happened in Killykeen Forest Park near Cavan town shortly after 3pm.
The teenager was taken from the water and transferred to Cavan General Hospital, where he was pronounced dead.
A post-mortem examination is to be carried out.
Separately, a five-year-old boy drowned after swimming in a pond in the Belgree Lawns area in Tyrrelstown, Dublin.
The boy had been missing since 9.30am this morning and was found an hour later.
Resuscitation attempts were unsuccessful and he was pronounced dead at Temple Street Children's Hospital at around 11am.
The pond is an artificially created lake in the park, which was opened by Fingal County Council last year.
There is a ban on swimming at the pond and there are warning signs and lifebuoys.
Gardaí are not treating the child's death as suspicious and have described it as a tragedy.
Fingal County Council said its thoughts are with the family.
It is the second drowning this month in a pond managed by Fingal County Council.
Ricky Oasagi, 13, died earlier this month in Waterville Park.
