Israeli Navy forces on their way to intercept an Iranian weapons shipment to the Gaza Strip took a short break from their duties last Friday evening to celebrate the coming of Shabbat and sing a festive song, a newly released IDF video shows.

The video, released by the IDF on Friday, depicted troops a week earlier on one the navy vessels that set sailed towards the Sudanese-Eritrean border on the Red Sea to take control of “Klos-C.”

The soldiers are seen singing “Shalom Aleichem” (Peace Be Upon You), a traditional Sabbath hymn that tells of angels accompanying a man home from the synagogue on the eve of the Sabbath.

One of the soldiers then picks up a wine glass and recites the traditional Shabbat blessing. “Amen,” the other soldiers answer in tandem, adding “Shabbat shalom!”

Israeli forces intercepted the ship “Klos-C” as it headed to a Sudanese port in an early morning raid Wednesday, 1,500 kilometers (930 miles) off the coast of Eilat.

They said the ship was laden with M-302 long-range missiles to be smuggled into Gaza via Egypt. The missiles, which Israel said originated in Iran, would allow rockets fired from Gaza to reach practically any location in Israel.

The ship was due to be brought to port in Israel on Saturday.
