A Jordanian court on Sunday leveled terrorism charges against a man suspected of wounding eight people in a November knife attack at the popular Jerash tourist site.

The suspect, Moustafa Abourouis, 22, faces up to 20 years in prison after the stabbing of three Mexicans, a Swiss woman, a Jordanian tour guide and a security officer.

At a hearing open to the press, prosecutors accused Abourouis of committing a “terrorist act” and “promoting the ideas of a terrorist group” — a reference to the ISIS group.

Abourouis, who is of Palestinian origins and grew up in the refugee camp of Souf, was arrested immediately after the attack at Jerash, close to the camp and around 50 kilometers (30 miles) north of Amman.

The Jordanian prosecutor accused Abourouis of trying to join ISIS, an operative of which in Syria had “ordered him to commit attacks against foreigners”.

Two alleged accomplices, also Jordanians of Palestinian origin, were charged with “terrorism” in the same case. All three pleaded not guilty, reported AFP.

The court is scheduled to hear witnesses next Sunday, with the date for a verdict to be confirmed.

In December 2016, in Karak, 10 people were killed in an attack claimed by ISIS that also left 34 wounded.

Four violent incidents struck the country the same year, including a suicide attack in June claimed by ISIS that killed seven Jordanian border guards near the frontier with Syria.
