A Palestinian student imprisoned for 50 days in Egypt appealed to Palestinian leaders on Monday to resolve his case. Rami Nimnim, 32, from Gaza City, wrote to the leadership via relatives saying he was being held in a section of al-Qanatir prison in Cairo for foreigners residing illegally in the country. Nimnim insists he has the right residency papers, and wants to complete his masters thesis in Cairo. He said the Palestinian embassy in Egypt had pledged to raise his case with the country\'s authorities, but accused envoys of neglecting him.
