The US says it has temporarily evacuated its staff from the Libyan capital Tripoli over security concerns. Staff, including marine guards providing security to the embassy, have been transferred to Tunisia "due to the ongoing violence resulting from clashes between Libyan militias," it adds. Secretary of State John Kerry said there was a "real risk" to staff. It comes amid fierce clashes between rival militias in the capital, with intense fighting at Tripoli airport.

November 4 is the 34th anniversary of the seizure of the U.S. Embassy in Tehran by Islamist students who held 52 U.S. diplomats hostage for 444 days. The 1979 crisis triggered a break in diplomatic relations between Iran and the United States and led to decades of mutual hostility. Today, the former embassy building houses a museum that is only occasionally open to the public. Here's a rare look inside the historic site.

On Monday, over 10,000 Iranians protested outside the U.S. Embassy in Tehran. World News reports the disruption occurred due to the anniversary of the 1979 seizure of the building, which permanently severed ties with the country and the U.S. Fifty-two hostages were taken captive in Iranian hostage crisis that lasted 444 days.

A U.S. Embassy staffer in Malta left the country on Wednesday after a video showing him going bonkers on another driver in the middle of a narrow road went viral. The American employee, apparently, confronted a Maltese driver who refused to pull over and let his car through. As traffic built up behind the driver, the American finally backs out of the road. And then, off camera, he continues to yell at the driver as traffic finally moves again.

In what a spokeswoman attributed to "an abundance of caution," the State Department decided late last week to close a host of American embassies in Africa and the Middle East, most of them in predominantly Muslim countries, due to concerns about possible terrorist attacks. This decision may have been prudent and was certainly based on extensive, if ambiguous, intelligence, but it should not become the norm.

The United States temporarily closed nearly two-dozen embassies and consulates last week, mostly in North Africa and the Middle East, with 19 set to remain closed for the rest of the week. The administration of U.S. President Barack Obama cited intelligence about potential terrorist attacks by al Qaeda in Yemen. On Tuesday, Washington stepped up security precautions in Yemen by ordering all non-emergency embassy personnel to leave the country and urging all U.S. citizens to depart immediately as well. Similar actions were taken by Great Britain.

The State Department has closed a total of 19 diplomatic posts in the Middle East, North Africa, and East Africa and has ordered the U.S. Embassy in Yemen evacuated. But what exactly does that mean for U.S. missions and U.S. citizens abroad? To find out, we talked to a current State Department Foreign Service officer who is on detail at the American Foreign Service Association, a union for diplomats.

The U.S. State Department closed its embassies in four sub-Saharan African nations as part of a heightened security alert, days before the 15th anniversary of al-Qaida's bombings of American diplomatic missions in Kenya and Tanzania. Those two embassies targeted in the Aug. 7, 1998, attacks were rebuilt as more heavily fortified structures away from populated areas where they would be less vulnerable to attack.
