CAIRO - Israeli envoy in Egypt Yaakov Amitai flew to Tel Aviv on Thursday to spend the weekend with his family, DPA reported, adding that he may not return Egypt before January 25, when celebrations will be held, in order to avoid any potential unrest. Egyptians will celebrate January 25 as a National Day. Amitai had already decided to take leave this weekend, when he assumed his post from former Ambassador Yitzhak Levanon in December. If the celebrations are calm, Amitai will return to work at his Maadi home by the week of 29 January. The Israeli Embassy has been closed since September, when it was raided by protesters who were angry over Israel's accidental killing of six Egyptian border police while chasing Palestinian militants across the Egypt-Israel border. The Embassy has yet to be relocated. On January 9, many political parties and movements called for nationwide protests on 25 January to demand a swift transfer of power from military to civilian authorities.
