KOTA BARU: Border enforcement agencies have stepped up security in Kelantan amid concerns over a rise in undocumented migrants entering the state by sea and land routes.

An integrated operation involving several enforcement agencies, coordinated by the National Security Council (NSC) and led by the police, was launched on Nov 7 to tackle human trafficking, migrant smuggling and other cross-border criminal activities.

A source said the operation, which runs until Nov 20, also involved the Immigration Department and Marine police.

The operation is being conducted from 7pm to 7am, covering both maritime and land border areas.
