Bangkok, Aug 15 (IANS): Authorities in Sri Lanka must ensure that voters have safe and secure access to the polls to vote in parliamentary elections on August 17, Human Rights Watch said on Saturday.

Local monitoring groups have reported numerous incidents of election-related violence and campaigning irregularities in the month leading up to the nationwide polls, it said.

The Centre for Monitoring Election Violence (CMEV), a longstanding independent monitoring organization, documented 135 major incidents, 10 involving the use of firearms, and 624 minor incidents between July 13 and August 13.

The major violations occurred primarily in Jaffna, Colombo, Batticaloa, and Gampaha districts. Three people have been reported killed and several injured.

"With evidence already of violence in the run-up to these elections, Sri Lankan authorities should take all necessary steps to protect voters and party supporters from attacks, threats, and intimidation," the rights body said.

"The authorities should also ensure that voters can travel safely and securely to the polling booths and back."
