July 17, Colombo: Visitors to the world famous Sigiriya rock fortress in Central Sri Lanka came under another wasp attack this morning, the police said.
At least 17 people including 12 foreign tourists were injured when they were attacked by wasps at the Sigiriya world heritage site on Sunday, according to local media reports.
The injured have been admitted to Sigiriya and Dambulla Hospitals and are currently receiving treatment.
The rock and the surrounding areas are home to wasp colonies and the visitors to the rock are instructed not to be noisy to keep the wasps undisturbed.
Authorities are reluctant to use chemical means to exterminate the wasp colonies for the fear of damaging the ancient frescoes.
