A Jordanian court on Tuesday sentenced three Syrians to five years in prison each for trying to smuggle 36 remote control detonators into their country to help the terrorist groups.

Civilian judges at the military state security court found the three men guilty of carrying out acts "that would harm Jordan's relations with another country, exposing the kingdom to the danger of reprisal acts," a judicial official told AFP.

They were also found guilty of entering Jordan illegally.

"They were sentenced to five years in jail," the official said.

According to the chargesheet, after crossing into Jordan from Syria last July two of the men settled in the northern city of Irbid while the third sought shelter in the Zaatari refugee camp near Syria's border, which is home to more than 100,000 Syrian refugees.

They started to communicate with some members of the Free Syrian Army in order to smuggle 36 detonators across the border, before their arrest in "an ambush" in September.

Jordan, which is hosting more than 500,000 Syrian refugees, has tightened border security and jailed dozens of men convicted of trying to enter war-torn Syria to fight alongside terrorist forces.
