A police roadblock close to the scene where an explosive device was detonated at Wattle Bridge (Picture: PA).
An explosive device has denotated in County Fermanagh while Army bomb disposal officers and police were at the scene.
The explosion happened in Wattle Bridge on the Cavan Road area on Monday morning at around 10:35 BST.
No one was injured.
Bomb disposal officers had been in the area at the weekend responding to reports that a device had been left there.
That item was ultimately declared a hoax but it is thought another device exploded close-by on Monday when a bomb disposal team attended to review the scene.
It is understood the Army team of Ammunition Technical Officers (ATO) and police were fortunate to escape without injury.
Fermanagh and South Tyrone MP Michelle Gildernew condemned the Wattle Bridge attack as "totally wrong".
The Sinn Fein representative went on to say those responsible for the incident "need to end these actions immediately".
Deputy Chief Constable Stephen Martin said: "While this investigation is at a very early stage I am of the firm belief this was a deliberate attempt to lure police and ATO colleagues into the area to murder them.
"Although this device was intended to kill police and Army personnel the fact that it was placed on a main road the result could well have been devastating for anyone in the immediate vicinity."
DCC Martin declined to be specific about the size of the device and how many officers were nearby at the time of the incident.
He went on to say the investigation is likely to examine whether either the Continuity IRA or the New IRA are behind the attack.
Anyone with details about the incident can call the police on 101 or information can be given anonymously via the independent charity Crimestoppers on 0800 555 111.
