The government today charged that controversial land reclamation work by neighbouring Singapore was affecting one of its naval bases, adding to a string of irritants between the two countries.

Defence Minister Najib Razak said the findings of a study by the navy had been handed to the foreign ministry for action, without giving further details.

Foreign Minister Syed Hamid Albar announced earlier this week that he would soon submit a scientific report to Singapore on the impact of the island-state's reclamation works in the Tebrau Strait between the two countries.

"We hope that with our submission they'll become more convinced of our own concerns, because our concerns are real," he said.
