The deadly attack on the US consulate in the Libyan city of Benghazi was planned and “meticulously executed,” the country’s assembly chief told AFP on Saturday.
He added that foreign elements could be involved in the attack.
“There are non-Libyan elements on Libyan soil and they plan to carry out their own agendas on our territory,” added al-Megaryef.
The revelations deepen the mystery surrounding the attack, as evidence comes to light that it was facilitated by “major security breaches,” according to the British Independent.
Intelligence officials received “credible information” of the raid 48 hours before, yet the mission’s usually robust security force made no effort to step up security measures, senior diplomatic sources told the newspaper.
It also revealed Stevens’ visit to Benghazi was considered confidential, making the attack more difficult to orchestrate.
“There was planning. It was not a peaceful protest which degenerated into an armed attack or aggression. That’s how it was planned,” he said.
The US announced Saturday that it would be sending more drones, Marines and spies to Libya, claiming to speed up the hunt for Stevens’ assailants.
US ambassador Chris Stevens and three other Americans were killed on Tuesday when suspected Islamic militants fired on the consulate in the eastern Libyan city with rocket-propelled grenades and set it ablaze.
Mainstream media initially assumed that the raid on the Benghazi consulate was a response to an anti-Muslim film that has been making the rounds on Youtube. But evidence of the attack as a pre-planned jihadi operation has piled up in recent days.
Sensitive documents have reportedly gone missing at the Benghazi consulate, apparently leading to attacks on secret refugee “safe houses”.
