There has been a fish kill on the Castletown River near Dundalk in Co Louth.

It is believed the source of the kill originated 20 miles away near Newtownhamilton in south Armagh.

The extent of the kill and the amount of contamination in the river is not yet known, due to the high level of water from recent heavy rainfall.

Brown and Sea trout have been seen floating in the river.
