From Ynet News, 6 Feb 2010, by Roee Nahmias:
Two Israeli missile boats pass through Egypt's Suez Canal en route to Red Sea, according to Arab media reports; Cairo adopts strict security measures to ensure ships' safety. Egyptian sources estimate vessels headed to Persian Gulf.
...The sail through the Suez Canal was coordinated with Egyptian authorities, which reportedly adopted strict security arrangements to ensure the safe passage of the two Israeli ships. According to Arab media, Egyptian forces prevented any vessels from passing through the Canal and also stopped the vehicular traffic on the road leading to it.
According to the reports, one Israeli missile boat already passed through the Suez Canal in June and July of last year. In one case, the Israeli ship was said to have been accompanied by an Israeli submarine.
Last week, Egyptian newspaper al-Shuruq reported that the US has been holding extensive maneuvers in the Persian Gulf, including some across Iran's shores. The report was based on information provided by senior Egyptian sources.
In addition, the newspaper reported that Israeli vessels have been mapping the Persian Gulf's waters in the past six months in cooperation with American forces belonging to the Fifth Fleet. However, it appears the report regarding Israel was baseless, and that it was leaked in an attempt to gauge Jerusalem's response.
