The United Nations has estimated that at least 230,000 people have fled ongoing violence against anti-government protestors in Syria.
Residents are leaving their homes and heading to nearby countries like Turkey, Lebanon, and Jordan.
Hundreds of people are crossing the Syrian border every day. Meanwhile, those still living in the troubled nation face harsh living conditions because of the skyrocketing cost of basic goods.
On Tuesday, Arab League Secretary General Nabil Elaraby called the actions of the Syrian regime "crimes against humanity."
He wants an international investigation into the alleged atrocities by Syrian President Bashar al-Assad.
"There must be an impartial international inquiry into what is happening to uncover those responsible for these crimes to face justice," Elaraby said in Cairo.
A French surgeon who recently treated wounded civilians near Homs, Syria, said his help was just a "drop in the bucket" compared to the overall need in the besieged city.
Dr. Jaques Beres testified Tuesday before the United Nation's annual human rights conference in Geneva, Switzerland. He said he saw many dead bodies and performed surgery on victims of mortar attacks.
Beres added that some 10 percent of the people he treated died on the operating table because of primitive conditions.
"The problem was not the great lack of medicine, it was more basic -- the lack of water and electricity," he explained. "We couldn't wash our hands. We didn't have brushes. We put alcohol on our hands and then we put on our gloves. We had a lack of electricity most of the day.
Beres is one of the founders of the Doctors Without Borders organization. He described the scene in Homs as "hell" and "unjustifiable mass murder."
