Two devices which police said were "capable of causing serious harm" have been found following security alerts in County Armagh.
Police said the devices have been made safe and removed.
The alerts followed the discovery of suspicious objects close to waterways, Lough Neagh and Camlough Lake.
When police shut the Newtown Road at Camlough Lake on Monday, they warned it was "likely to remain closed for some time".
A section of Lough Neagh's southern shoreline at Maghery was also shut.
Officers have not yet said when they are likely to reopen.
Ch Supt Andy Freeburn urged anyone with information to contact police.
He said: "These devices were of crude construction, but could have caused serious harm.
"We are at the very early stages of an investigation and are keeping an open mind as to the motivation. "I would like to thank local communities for their support and patience as we worked to keep people safe."
Both devices are being forensically analysed by the police.
