AGHIOS EFSTRATIOS: Two senior police officials have returned from an inspection tour of the internment camps on the island of Aghios Efstratios, in the northeastern Aegean, where some 540 communists are being held, and will file their report to the Interior Minister within the day. The officials were not able to speak privately with the inmates due to the communist system of mutual surveillance that prevails there. They saw that the exiles are mostly unrepentant communists and idlers who have never worked but sit around and talk politics at every opportunity. According to these officials, they are to propose the release of some of the more aged and infirm inmates. They will also assert that charges by a United Democratic Left (EDA) deputy regarding poor living conditions and harsh treatment at the camp are completely unfounded. KARAMANLIS AND NASSER: Prime Minister Constantine Karamanlis yesterday gladly granted an audience to Egyptian Ambassador Hassan Mohammed el-Hakim who gave him a personal message from President Abdel Gamal Nasser as well as an official invitation to visit Egypt, which Karamanlis accepted.
