Sri Lankan police recovered 14 motor bombs in the area of Omanthai, Vavuniya last week.
A resident in the area noticed suspicious objects in the well, and informed the Omanthai police.
Following this lead, the police and Sri Lankan Special Task Force (STF) troops retrieved and defused the 14 motor bombs.
Since the end of the bloody war in 2009, there have been several findings of this kind in the North-East.
