American terrorism expert Sidney Jones has resumed her work in Indonesia after her entry ban was lifted by the government last week. Marking her first public appearance after the lifting of the ban, she addressed a two-day international conference on security challenges in the Asia-Pacific region in Jakarta, which began on Tuesday. Jones, director of the Jakarta office of the Brussels-based International Crisis Group (ICG), arrived here last Friday. "As a researcher, my client is free to conduct studies and to share views, attend seminars or to visit conflict-prone areas in Indonesia," Jones' lawyer Todung Mulya Lubis said. "I will file a protest if any restrictions are imposed on her in carrying out her work, which includes visiting conflict zones such as Aceh, Papua and Poso," he added.
