Sri Lanka's cricket board said on Wednesday it had received warnings its national team could be the target of a terror attack during an upcoming tour of Pakistan.
The board said the Sri Lankan Prime Minister's Office had advised it to "reassess the situation" after it received "reliable information of a possible terrorist threat" against the national squad ahead of the six-match limited-overs tour.
It stopped short of calling off the tour, but said a reassessment of the security situation would be sought from Sri Lankan government authorities.
The Sri Lanka team was the victim of a terror attack during a Test match in Pakistan's Lahore in March 2009. Six Sri Lankan players were injured when gunmen attacked their bus while six Pakistan policemen and two civilians were killed.
The statement from Sri Lanka cricket board came a short while after the board announced two squads for the three One-Day Internationals and the three T20 matches starting September 27.
Since the 2009 attack, a majority of international teams have refused to tour Pakistan.
Sri Lanka named depleted squads for a six-match tour of Pakistan after 10 top players opted out citing security concerns.
Lahiru Thirimanne has replaced one-day international skipper Dimuth Karunaratne, who refused to join the tour along with Twenty20 skipper Lasith Malinga.
Thirimanne will lead a 15-member ODI squad, while the 16-member T20 squad will be led by Dasun Shanaka.
The other eight players who opted out of the Pakistan tour are Thisara Perera, Angelo Mathews, Niroshan Dickwella, Kusal Perera, Dhananjaya de Silva, Akila Dananjaya, Suranga Lakmal and Dinesh Chandimal.
