Sri Lankans are debating fishing rights a day after a navy patrol boat was blown up by a craft two survivors say was hidden among civilian fishing boats.
The government blames separatist Tamil Tiger rebels for Saturday's attack that killed at least 13 sailors.
The rebels Sunday accused the Sri Lankan navy of banning Tamils from fishing, saying a thousand families have been affected by the ban.
Associated Press reports a navy official denies a ban is in place, but says the navy is strictly enforcing restrictions on fishing outlined in the cease-fire agreement with Tamils.
The French news agency, AFP, reports the navy has banned fishing at night near the port of Trincomalee.
Sailors that survived the blast say the explosives-laden boat that rammed the navy vesel just outside the port Saturday night was initially concealed among civilian fishing boats.
