The return of the unknown Yemenis and Ethiopians to the Saudi lands from Yemen once again after expelling them constitutes a serious danger on the security of the Kingdom due to the dangers associated with them including the drugs and the various kinds of weapons. This return has been occurring through the help provided to them by the smugglers for entering into the Saudi lands in addition to transporting them to the various areas of the kingdom. The numbers of the unknown persons has been increasing constantly in Jazan to the extent of that it has become a danger threatening the regional citizens, putting into consideration that they are groups of unknown people, beggars and drugs promoters. Al-Riyadh has been present in the field there as it monitored, through pictures, some of the sneakers and had discussion with them where it has been discovered through the initial observation that most of the sneakers arrive through "Al-Mashnaq" area in Yemen which is a rough mountainous area close to Saudi Arabia from the Eastern side.
