Egyptian Prosecutor-General Maher Abdel Wahed said Saturday that initial investigations showed an explosion occurred late Thursday which killed three people was an individual act.

"The investigations have proven that this was the act of an individual, not a group," Wahed told reporters at a press conference, without revealing further details.

The prosecutor also said no one can make any speculation and everyone must wait for the outcome of the investigations, stressing that the investigations will continue.

Meanwhile, Wahed increased the number of people injured in the attack from the original 18 to 19, adding a French casualty is to be flown home for treatment.

The three dead included an American man, a French woman and an unidentified man who is suspected by the police to be the suicide attacker.

An Egyptian investigator, speaking on condition of anonymity, said the severe damage to the suspected bomber's torso increased suspicions that the culprit was a suicide attacker.

Police are still looking for his hands to check his fingerprints and investigators are running DNA tests on his remains.

However, in an Internet posting on Friday, a previously unknown Islamist group claimed it was behind the bombing.
