Turkey's Prime Minister Recep Tayyip Erdogan is due to meet with Egypt's military rulers when he visits Cairo today at the start of a tour of so-called Arab Spring states.
The visit comes some seven months after longtime ruler Hosni Mubarak was ousted as Egyptian president amid mass public protests.
It also comes with Egypt on an official high security alert after a mob on September 9 stormed the building housing the Israeli Embassy in Cairo, during riots in which at least three people died and more than 1,000 were injured.
Turkey has expelled the Israeli ambassador to Ankara in protest over Tel Aviv's refusal to apologize for last year's Israeli raid that killed nine Turks who were taking part in an aid flotilla to the Palestinian Gaza Strip, which neighbors Egypt.
After Egypt, Erdogan is expected to visit Tunisia and Libya, where, like Egypt, longtime rulers have recently been overthrown.
