The Sri Lankan navy attacked fishermen from India with nylon ropes and pelted stones at them on Tuesday morning, in the third reported attack by Sri Lankan security forces on Tamil Nadu fishermen this week.

The fishermen from Ramneswaram were reportedly set upon by the Sri Lankan navy, who attacked them off the coast of Katchatheevu and warned them not to return.

The attack comes after Sri Lankan Prime Minister Ranil Wickremasinghe reiterated his defence of the Sri Lankan navy's shooting at Indian fishermen who stray into its waters.

Sri Lanka's cabinet on Sunday approved the draft bill on the 19th Amendment to the constitution, amending powers vested with the executive president.

Reforms will include the reduction of the president's term from six years to five years and transferring the power to dissolve parliament from the president to parliament itself.

"The Presidential immunity from being sued over matters conducted during his period of office is to also be removed under the proposed reforms," reported Sri Lankan government's news site.
