On the firing and rocketing sources, Asiri said that the topography of the border areas, between the Kingdom and Yemen is mountainous, arid and difficult, so to have a number of infiltrators holding mortar shells may inflict damage on border centers etc, for the militia are on the move and do not have constant sits, but we engage, at all borders, at the dame grade of readiness and alert. Sources of fires, field canon, fire launchers, Apaches and Air Force planes are engaging the situation as that will not happen without being punished. Najran is a border city and the distance of mortar shells are different, as there are Mortar 80 and Mortar 120, and their ranges are varying due to the different angles of shelling and that is also the case for the Katyusha missiles, Asiri pointed out, asserting that the sources of fire have been identified and that the Land Forces have tackled the situation and is confronting the source the militias' launchers. There is work on the ground and you will watch it, as soon as possible, Asiri commented. The fires are indirectly fired, because you can fire from behind a cover, and that was the case of the shells that hit Najran, but the Land Forces and the Border Guard are doing their jobs and that there are a commitment from the coalition command that there during the Operation Determination Storm, that there will be a reaction if anything happened, because the coalition command attempts to tranquilize and give a role for the political spectrum and the relief works, but unfortunately these militias, wrongly, understand the message and thought that they could take advantage of the situation and affect the security and the safety of the border, as well, he said. On expecting any development, on the movement of the coalition forces, following the shelling of Najran today, he said that all options are open before the command of the coalition, to take the appropriate measurements to guarantee the security and safety of the borders of the Kingdom and that these militias will not be allowed to repeat what has taken place, here today as full procedures and options, are at stake. -- SPA 22:05 LOCAL TIME 19:05 GMT www.spa.gov.sa/w
