COLOMBO, Sri Lanka (AP) — Sri Lanka’s former president says the government’s secret services are conducting constant surveillance on her and she fears for her safety.

Chandrika Kumaratunga says her telephone calls, emails and her two residences are under constant surveillance and her friends have been interrogated by secret service officials after they visit her.

She sent a letter to her successor, President Mahinda Rajapaksa, alleging his government violated her privacy, harassed her and caused her to be concerned for her personal safety. The letter dated March 5 was seen by The Associated Press on Friday.

The president’s office rejected the allegations, saying it lacks proof to justify “such charges of a serious nature.”

The Sri Lankan government is facing mounting criticism for arresting human rights campaigners and resisting calls to investigate alleged war crimes.
