Warring militias fight for Libya's capital

Fighting between rival militias has continued to rage in Libya's capital forcing thousands to flee the country and prompting a number of embassies and international companies to evacuate their staff. At least seven people have died in the latest round of violence, less than a week before the UN sends a special envoy to help broker a ceasefire. But there's been opposition from thousands of Libyans who see it as foreign intervention. Al Jazeera's Caroline Malone reports.
