Egypt and Pakistan are dismissing reports that Pakistanis were involved in Saturday's bombing spree in Sharm al-Sheikh that killed nearly 90 people.
Both governments issued their denials Tuesday, hours after Egyptian media and satellite television carried pictures of five Pakistanis whose passports were found near the resort.
In other developments, Egyptian police are reported to be looking for links between Saturday's attacks and two Sinai bombings last year that killed 34 people near the Israeli border.
The possible link became known after two militant groups that claimed responsibility for Saturday's blasts said they also carried out attacks last October at and near a resort in Taba.
Western news reports say DNA samples from the remains of two bombers killed in Saturday's blasts will be compared to that of the parents of five fugitive suspects in the Taba bombings.
