President Rajapaksa in discussions with members of the Presidential Commission of Inquiry (PCoI) to investigate and inquire into the Easter Sunday terror attacks, said there was an urgent need to identify roots and modalities of the April 21 suicide attacks and uncover all information related to the attacks.
The president said the security situation was continuously reviewed with intelligence officers.
"If there was any information that threatened national security, necessary action was taken in no time. That was how we were able to deport 160 preachers who were propagating extremist ideas," the president informed the PCoI.
The president further requested the PCoI to make recommendations to prevent recurrence of such tragedies, adding that maintaining national security was of utmost importance.
President Rajapaksa also offered to provide all necessary facilities required by the special commission.
Over 250 people were killed in the April 21 suicide attacks which targeted three churches and three luxury hotels across the Island country.
A local extremist group named the National Tawheed Jammaat were identified to be responsible for the attacks, the police said.
