Suspected dissident republicans behind a cache of arms discovered in Strabane have been described as "deluded" by West Tryone MP Pat Doherty.
The Sinn Fein man was speaking after police searches at a graveyard on Sunday and Monday uncovered suspected handguns, petrol bombs and two suspected pipe-bombs.
Detectives from the PSNI Serious Crime Branch investigating dissident republican activity carried out the searches which netted the arsenal, but no one was arrested during either operation.
Area commander Chief Inspector Andy Lemon said the weapons were potentially lethal.
He said: "The pipe-bombs were found in the cemetery in Strabane – an area where people go to pay their respects to the deceased.
"It is a very worrying development that these two viable devices with the potential to kill or maim were found in a hedgerow alongside this cemetery.
"Over this weekend we recovered two firearms with ammunition, two viable pipe-bombs and two petrol bombs and I am glad that we have them because it means we are protecting lives, the lives of the community and the lives of our officers."
No arrests were made.
