These twelve people were killed during a clash between guards and a group of 36 people from Syria, some of them armed, who were trying to cross the Jordanian border, said an official from the general command of the armed forces.
According to this official, quoted on the website of the general command of the armed forces, an undetermined number of people were injured during this confrontation and others fled and returned to Syria.
More than two million narcotic pills were seized by the guards, he added the same source.
Jordan has been shown to be worried that the jihadis infiltrated entry among the refugees, thus justifying the restrictions to host Syrian refugees who are on its borders, estimated at around 16 thousand.
The kingdom authorizes the daily passage of dozens of Syrians and imposes a strict identity check.
According to the United Nations High Commissioner for Refugees (UNHCR), Jordan hosts more than 600,000 of the four million Syrians who fled the war in their country since 2011.
