A warning has been issued to Americans to avoid travel in Algeria after protestors attacked the U.S. Embassy in Libya, killing four Americans.

The U.S. Embassy in Aligers is advising Americans to avoid travel to the area around the embassy if possible as protests may be held in the majorly Islamic country, following protests that took place in Libya and Egypt. Several Algerian groups have taken to social media to organize demonstrations at the U.S. Embassy in Algiers. The embassy is warning Americans to avoid all non-essential travel near the embassy or other official buildings.

This warning comes after a protest was held at the U.S. Embassy is Libya which led to four Americans being killed, including U.S. Ambassador to Libya, Christopher Evans. The protests were led by Libyan religious extremists who stormed the U.S. Consulate in Benghazi on Tuesday night.

"It is with profound sadness that I share the news of the death of four American personnel," said U.S. Secretary of State Hillary Clinton in a statement.

President Obama also paid his respects to the diplomats who were killed.

"They exemplified America's commitment to freedom, justice, and partnership with nations and people around the globe, and stand in contrast to those who callously took their lives," President Obama said in a statement.

Also on Tuesday, protestors in Egypt held a demonstration at the U.S. Embassy in Cairo. Protestors tore down the American flag outside of the building.

All of these protests are being held in response to an anti-Islam film by an Israeli-American real-estate developer, Sam Bacile. In the film, "Innoncence of Muslims," the 52-year-old mocks Prophet Muhammad. Baile raised $5 million from 100 Jewish donors to create the film that has Islamic extremists outraged.
