Syrian tells of horror in Homs, then line goes dead Syrian tells of horror in Homs, then line goes dead - Mideast & N. Africa 'I think I will die,' man in Syria's besieged city of Homs says - then the line goes dead 'Got to go because there is a fire,' man says, then an explosion and silence A resident of the besieged Syrian city of Homs said on Friday that he feared for his life, shortly before a blast cut off the conversation he was having with NBC News. "No one can protect themselves from shelling in (the neighborhood of) Baba Amr," Abu Bakr told NBC News producer Michele Neubert via Skype as government troops pounded the area. We just need (to) stop the shelling. I'm hungry from two days. I'm eating just some onions (for) two days. That's my life, that's the life in Baba Amr," he said. Most people here eat just simple things, the plants on ground. When asked about his future, Bakr said: "I think I will die." Minutes later, he said, " (I've) got to go because there is a fire." Neubert then heard a loud explosion, after which the line went dead. Earlier in the conversation, Bakr said he had been in the same house where Marie Colvin, an American working for Britain's Sunday Times, and French photographer Remi Ochlik, were killed Wednesday. 'Urgent' need for help He said the international community must take action. "It is urgent that you have humanitarian corridor in Syria," he said. This could save the lives of a lot Syrians. Two journalists wounded in the same attack that killed Colvin and Ochlik were also awaiting evacuation from Homs. Activists say the army is stopping medical supplies from getting into the city and electricity is cut off for 15 hours a day. Bakr criticized Russia and China, which have blocked efforts to pressure Assad's regime in the United Nations. " (On one hand) they are talking about preventing ... external intervention in Syria, and on other hand they are sending the weapons and the mercenaries to Syria to support Assad's crimes," he told NBC News. Neubert told msnbc.com after the conversation that NBC colleagues had been calling their contacts in Syria to try to find out if Bakr was okay. It's so difficult to reach anyone there. It's proving almost impossible to clarify what happened, but we are endeavoring to do so," she said. As government troops continued to pound rebel-held neighborhoods in Homs, thousands of people in dozens of towns across Syria staged anti-regime protests under the slogan: "We will revolt for your sake, Baba Amr." Meanwhile, more than 70 countries were taking part in Friday's "Friends of Syria" meeting in Tunisia, which is expected to press President Bashar Assad to agree to a cease-fire and allow for humanitarian aid to reach the areas that have been hardest-hit by his security forces. Syria rebels: Let us have the weapons to finish Assad American, European and Arab officials have said the group would likely impose harsher sanctions if Assad rejects the cease-fire, and predicted the regime's opponents would grow stronger if Assad remained in power. The U.N. estimated in January that 5,400 people had been killed in the conflict in 2011. Hundreds more have died since. Syrian activists say the death toll is more than 7,300. Overall figures cannot be independently confirmed because Syria has prevented most media from operating inside the country. Assad's security forces blames the uprising on Islamic extremists and armed gangs. The opposition, boosted by army defectors, has increasingly taken up arms against the regime.
