Several tourists were stabbed on Wednesday in Jerash, a Jordanian city popular with foreign visitors, along with a local guide and a security guard, police said, adding that a man had been arrested.
A security source told Reuters the victims were three Spanish women who were taken to hospital. A civil defence source said their injuries were minor. No further details were immediately available.
Jerash is well known for its Roman ruins.
