The cityt of Jerash is the location of well-preserved Roman ruins and is popular with tourists.
An amateur video from the scene at the Jerash site showed a woman screaming in Spanish: "It's a dagger, it's a dagger, there is a knife. Please, help him now!"
One woman is seen lying on the ground, with blood around her, as someone presses a towel to her back. Another man sits nearby with an apparent leg wound.
The al-Ghad newspaper said the tourists were Mexican and suffered serious wounds.
