As Israel keeps threatening the regional countries with war, Egyptian maritime sources say the Israeli navy has deployed two missile ships to the Persian Gulf.

Citing the sources, Yediot Ahronot reported Saturday that two Israeli missile ships passed through the Suez Canal en rout to the Red Sea on Thursday morning.

The sources said the ships are expected to reach the Persian Gulf within the next four days.

According to the report, Cairo adopted tight security measures to ensure the safe passage of the Israeli ships through the canal.

The waterway, which had not previously been used by Israeli vessels for intelligence reasons, was traversed for the first time in June 2009 when a Dolphin-class submarine (a nuclear German-made submarine) reportedly sailed from the Mediterranean to reach military exercises in the Red Sea.
