Reacting to the report, Sri Lankan army today strongly denied it saying they have request the UN expert to provide any evidence so that an investigate can be launched.
"The Army is aware of this story. We have at all times clearly said that the Army never used cluster bombs during our operations. We understand that the story had been based on a report filed by a gentleman named Allan Poston.
We request him to provide us with any evidence he may be having so that we could investigate," military spokesperson Brigadier Ruwan Wanigasuriya told reporters here.
"I wish to reiterate that Sri Lanka Army, Navy or Air Force never used cluster bombs," the spokesman said.
The report said an email obtained by them from a top UN demining expert had said that unexploded cluster bombs were discovered in the Puthukudyiruppu area in the north.
The area known as PTK was a LTTE nerve centre during their decades old fight with the government troops.
Thousands of civilians crossed over to the areas of government control from PTK during the last battle which ended in May 2009. PTI CORR AKJ
