A court in Jordan on Monday ordered six men jailed for waving the Islamic State group’s flag and singing jihadist slogans at a wedding, AFP reported.

The state security court sentenced two defendants to five years in prison for “carrying out acts that expose the kingdom to the risk of hostile acts and ruining relations with foreign states,” according to the report.

The remaining four were sentenced in absentia to 15 years, after they failed to show up for trial.

The defendants were arrested shortly after the wedding in September in the northern city of Irbid, according to the indictment seen by AFP.

It said the defendants had adopted an extremist ideology and had distributed propaganda at religious centers in Irbid, which is close to the Syrian border.

Amman has arrested and imprisoned dozens of jihadists for trying to sneak into Syrian territory to fight there.

ISIS controls large areas of Iraq and Syria, both of which border Jordan, and has imposed its brutal interpretation of Islamic law.

Jordan last year joined the international coalition carrying out air strikes against IS positions in Syria and Iraq.

In February, ISIS burned alive a Jordanian pilot it had captured after his F-16 jet crashed while on a mission over northern Syria.

Jordan responded by executing two jihadist prisoners it had held, and later launched airstrikes against dozens of ISIS targets.
