Colombo, July 31 : Domestic flights to northern Jaffna are likely to be suspended during the 15th South Asian Association for Regional Cooperation (SAARC) Summit.
SAARC leaders are meeting in Colombo between August 1 and August 3.
Sri Lankan Civil Aviation Authority Director General Parakrama Dissanayake said that during these days, flights by domestic carriers between Colombo and Jaffna would be suspended for security reasons.
Meanwhile, a heavy security blanket has been imposed across Colombo for the summit.
Sri Lankan defence forces have been placed on high alert for possible attacks by the Liberation Tigers of Tamil Eelam (LTTE) during the summit. The military is also on alert.
The Sri Lankan air defence system now covers key installations in and around Colombo as well as approaches from northern jungles where the Tigers have their bases.
