Jordan: knife attack against tourists

A knifeman has injured four foreign tourists and four locals in an attack in the Jordanian city of Jerash.

Three Mexicans and a Swiss national were among the wounded. One of the Mexicans and a Jordanian tour guide were hurt seriously, the health minister said.

The suspected attacker was arrested nearby by police.

Jerash, home to a well-preserved ancient Roman site, draws thousands of foreign visitors every year.
