Libya's president says the attack that resulted in the deaths of U.S. Ambassador Christopher Stevens and three other Americans at the U.S. consulate in Benghazi was a “pre-planned attack of terrorism.”

In a Wednesday interview with the U.S.-based “NBC News,” President Mohammed el-Magarief said the attack had nothing to do with protests against an anti-Islam film.

“It was launched with a high degree of accuracy which means that the perpetrators must have had some kind of exercise on how to hit, how to launch this act.”

U.S. officials have also called the attack earlier this month an act of terrorism. The assault took place on the anniversary of the September 11, 2001 terrorist attacks in the United States.

The incident took place as thousands of Muslims were protesting against a video produced by an anti-Muslim filmmaker in the United States.

In a speech Tuesday to the U.N. General Assembly, U.S. President Barack Obama called the video “crude” and “disgusting.” But, he said no video justifies an attack on an embassy.
