Occupied Palestine (QNN)- An Israeli submarine openly crossed last week the Suez Canal en route to Iran in a show of force, Israeli public broadcaster Kan reported on Monday. Citing Arab intelligence sources, the Israeli channel said the move was conducted with Egypt’s approval and in the midst of seething tensions between the occupation state and Iran. According to Israeli media, the submarine passed the Red Sea and was making its way toward the Persian Gulf, in what they believe was meant as a direct threat to Iran. The tension between the occupation state and Iran has increased dramatically following the assassination of the Iranian nuclear scientist Mohsen Fakhrizadeh on November 27. Shortly after the assassination, Iran vowed revenge on the occupation state, which is believed to be behind the assassination.
