Investigations revealed that no armed group was behind a gunman's attack on a group of tourists in downtown Amman on Monday, which killed a British man and injured six others, including a policeman, local newspaper Jordan Times reported Tuesday.

"Investigations showed that the criminal attack was a sole act carried out by 38-year-old Jordanian Nabil Ahmad Issa Jaaoura, who had no ties to any armed groups or suspicious links with other groups inside or outside Jordan," government spokesman Nasser Judeh was quoted as saying.

A gunman opened fire at a group of foreign tourists and their guide in Amman's Roman Amphitheater on Monday, killing a Briton and wounding six others.

Besides one Jordanian policeman, the injured also included two British women, a Dutch man, an Australian woman and a New Zealander woman.
