Al Jazeera has obtained video of three western hostages from Britian, Sweden, and the Netherlands. The hostages claimed their governments are negotiating with al Qaeda in the Islamic Maghreb for their release. More than 250,000 Malians have fled the country after Islamist groups took control of the north.
