The pictures you see in this link are photos of people evacuating from Chad.

The pictures in question were taken by a UN satellite camera that was trained on that particular city. The picture in question shows 10,000 people who are trying frantically to cross the border from Chad to Cameroon.
Doctors without Borders is trying to assist:
MSF has been trying to assist over 10,000 refugees from Chad, now settling in Camerooon. In this interview with Hugues Robert, Program Manager of the MSF (Swiss) Emergency Desk, MSF explains the range of work currently underway and the wider issue of people in need throughout the area.
Reports say that 30,000 people are still trapped in West Darfur, Sudan, facing aerial bombing and ground attacks and MSF is very worried about this civilan population.
The refugees are trying to escape ground and air attacks. This is the sort of madness that we are up against on a regular basis. While the Bush administration is continuing to engage in scaremongering and promoting the McCain Doctrine of Perpetual Warfare in Iraq, they have made themselves completely paralyzed and unable to respond effectively to the violence in Sudan and other hot spots in Africa.
The world is waiting for a powerful and effective American response. But the American that they once knew is no longer there. The Bush administration has shot our credibility full of holes with their propagation of perpetual warfare and their massive human rights violations, including the use of torture, renditions, and the bombings of civilian populations.
Al Gore was the rightful winner of the 2000 elections. But five SCOTUS justices thought that they knew better than the American people and Florida voters who should serve as our next President. And now, we are paying the price and the blood is on these justices' hands. If Al Gore had become the rightful President, he would have capped the hard work of the Clinton administration, capped the Israel-Palestine peace talks, given us much credibility around the world, and given us standing to stop this conflict a long time before it got to the point where it is now. Instead, we have an administration which is completely paralyzed and which is doing absolutely nothing about this crisis.
Edit -- This just came in. Crandall Canyon Mine Owner showed callous disregard for the law:
The owner of the Crandall Canyon mine in Utah where six coal miners and three rescue workers died last year showed a "callous disregard for the law and for safety standards, and hardworking miners lost their lives," says Sen. Edward Kennedy (D-Mass.), chairman of the Senate Health, Education, Labor and Pensions Committee. The committee issued its report on the disaster today.
Kennedy says the U.S. Justice Department should begin a criminal investigation into the circumstances that led to the Aug. 6 collapse that killed six miners—whose bodies have never been recovered—and the Aug. 16 deaths of the three rescue workers.
You may think that these two issues are not related, but they are. What both these stories have in common is the callous disregard for human life that both George Bush and John McCain have. George Bush showed callous disregard for the law in his invasion and occupation of Iraq. John McCain's disregard is even worse, given the fact that he supports 100 years of warfare in Iraq. And this carries over to other issues -- the Crandall Canyon disaster, the neglect of Chad and other hot spots in Africa, the threat to invade Iran.
Any country that is built on the exploitation of resources is inherently unsustainable. The Roman Empire collapsed after it had reached its limits and could not extract the wealth from new conquered countries. Other empires in the past have also collapsed in the same way. Ours will as well if we do not change our ways.
