WASHINGTON (AP) - The Obama administration was caught by surprise by the ferocity of the Sept. 11 attack against the U.S. Consulate in Benghazi, Libya, that killed the ambassador and three other Americans. Now it is bracing for another potential eruption of violent demonstrations in parts of the Muslim world after Friday's weekly prayers _ traditionally a time of protest in the Middle East and North Africa.
Angry demonstrations over an anti-Islam video already have occurred in Egypt and Yemen, and officials theorize that well-armed Libyan extremists hijacked a similar protest in Benghazi, where several Libyan security guards also were killed. The U.S. put all of its diplomatic missions overseas on high alert, and Secretary of State Hillary Rodham Clinton delivered an explicit denunciation of the video as the administration sought to pre-empt further turmoil at its embassies and consulates.
"The United States government had absolutely nothing to do with this video," she said before a meeting with the foreign minister of Morocco at the State Department. "We absolutely reject its content and message."
"To us, to me personally, this video is disgusting and reprehensible," Clinton said. "It appears to have a deeply cynical purpose: to denigrate a great religion and to provoke rage."
U.S. officials said they suspect that the attack at the Benghazi consulate, which had also been the target of an unsuccessful attack in June, may have been only tangentially related to the film.
They also stressed there had been no advance warning or intelligence to suggest a threat in Libya that would warrant boosting security, even on the 11th anniversary of the terror attacks of Sept. 11, 2001.
"As we did with all of our missions overseas, in advance of the September 11 anniversary and as we do every year, we did evaluate the threat stream and we determined that the security at Benghazi was appropriate for what we knew," State Department spokeswoman Victoria Nuland said.
The intelligence leading up to the attacks will be examined to "see if there was any way of forecasting this violence," as in any violent incident, House Intelligence Committee member Adam Schiff, D-Calif., said in an interview Thursday. But he said the focus now "has to be on finding out who is responsible and bringing them to justice."
President Barack Obama, speaking a campaign event in Golden, Colorado, also vowed that the perpetrators would be punished.
"I want people around the world to hear me," he said. "To all those who would do us harm: No act of terror will go unpunished. I will not dim the light of the values that we proudly present to the rest of the world. No act of violence shakes the resolve of the United States of America."
As of Thursday morning, there was no intelligence indicating that what happened in Benghazi was planned, according to two U.S. officials briefed on the investigation into the attack. Intelligence officials said they believe it's more likely that the attack was "opportunistic or spontaneous," with militants taking advantage of the demonstration to launch the assault. The officials spoke on condition of anonymity because they were not authorized to discuss the ongoing investigation publicly.
There is also no evidence that the attack was tied to 9/11, one of the officials said. But the Libyan-based militant group Ansar al Sharia is the leading suspect for carrying out the violence, possibly with help from al-Qaida's main African-based offshoot, Al-Qaida in the Islamic Maghreb. The officials said it may be hard to determine definitively which group was responsible, because many militants are members of both.
Libyan officials arrested an unspecified number of militants suspected of taking part in the attack and they were closely monitoring others to see whether they are linked to a group.
Despite the belief that the militants who hit the consulate did so separately from the protests over the film, U.S. officials are deeply concerned that extremists may take advantage of non-violent demonstrations to copycat the Benghazi raid, or that otherwise peaceful protesters may be incited to attack because of the video, particularly on Friday.
It's virtually impossible to predict when a crowd might form and turn violent, according to retired U.S. Ambassador John Negroponte, who served as chief of mission at five posts, including Iraq, and is a former director of national intelligence.
"These things can be mobilized on the spur of the moment, set off by a spark," especially in places such as Egypt and Libya where the ruling strongmen have just fallen, Negroponte said Thursday. "When you get rid of authoritarian regimes, there's little or no institutional framework left. ...That's why there's disorder and chaos" that is so easily hijacked, he said.
