Hours after Saudi Arabia forces and Houthi rebels traded heavy artillery fire, Saudi-owned media reported the country is sending a "strike force" to its border with Yemen.Al Arabiya Hadath TV broadcast pictures of a column of tanks loaded onto military trucks and described it as "the arrival of reinforcements from the strike force to the border".

 The fighting between Yemen's Shia rebels and Saudi forces in border areas came a day before a humanitarian ceasefire was due to take effect.on Monday,

Apparently a "Moroccan F-16 fighter jet taking part in the Saudi-led coalition against the Shia rebels, known as Houthis, has gone missing, Morocco said"

The Moroccan jet vanished at around 6pm (4pm UK Time) on Sunday, the Moroccan military said.

It was not clear what happened to it and there has been no word from the Houthis - which routinely fire anti-aircraft guns at warplanes of the Saudi-led coalition.

The Houthis said they fired Katyusha rockets and mortars on the Saudi cities of Jizan and Najran, after the Saudis hit Saada and Hajjah provinces with more than 150 rockets.

 Saudi planes also struck positions of the Houthi group in the central city of Taiz and in the oil-producing Marib province, east of the Yemeni capital Sanaa.

There were no immediate details on any casualties.

Air strikes by Saudi Arabia and other Sunni countries jets have been targeting the Houthis for about six weeks now, but have so far failed to push them back.

Was the plane shot down by the Houthis as some media outlets are claiming?Is Morocco claiming the plane is down, so no ceasefire will take place?Particularly when one considers the additional troops being wrangled up?
