Heavy fighting has subsided in Chad's capital after breaking out at dawn, between government troops and rebels trying to overthrow the president.
The following comments reflect the balance of opinion we received:
Government forces have been issued with red arm bands and red ribbon to identify themselves. There are now large numbers of them circulating in the streets nearby.

We woke this morning to sounds of mortaring and heavy gunfire outside Geneina. The information we have is that the fighting is occurring on the Chad border near Adre. Last night at around 10:00pm we were aware of a number of large trucks moving out of Geneina which was unusual considering the recently tightened curfew in the town.

I was in N'Djamena two weeks ago, travelling through from Maroua, Northern Cameroon. In common with much of Central Africa, there is always a large military presence around - perhaps this was more in evidence after some rebels tried to shoot down Deby's plane the week before. I suspect the presidential elections that are due soon will only add to the tension, unfortunately. The military seems powerful, but not very well controlled - always a difficult situation.

Please let our president negotiate with these rebels. If he truly love his people. Since 4:30am this morning There has been fierce gun battle in our area and it is heading toward centre town. My advice to our president is that, Mr President please leave power before you become like Liberia former president Mr Charles Taylor.

There are reports of many government soldiers deserting and joining rebels on the outskirts of the capital. Idriss Deby has already left the capital and his whereabouts are not known. He reportedly transfered $430 million to a Swiss bank account on Monday. His close associates are said to be looking for asylum in South Africa and France.

You should stop the war because it is not important. If the war can bring a new today we will progress. Our country will progress. It is not important. Thank you.

I'm a Sierra Leonean that was in the country from the start to the end of the rebel war in our country. The only solution to resolve rebel wars is the willingness of the government to genuinely promise the rebels with political positions which I believe is their reason for rebelling. Let the Chad government use the experience we used to settle our problem. No amount of fighting can resolve a rebel war. The bushes are vast, soldiers can't move through them to kill all the rebels.

This morning there was heavy gunfire between rebels and governmental forces and also lots of heavy artery gunfire around the presidential palace. Once again the population is caught in between gunfire and trying to escape the capital city to have refuge in neighbouring Cameroon. Rebels penetrated to N'djamena earlier this morning - one group coming from Nala, 45km north-east of the capital, and the other from Dourbali. There are a lot of dead bodies on the street; I can even see them from the window.

I am here in N'djamena, Chad, working for a telecomm company, together with other ex-pats. Tension is really high in the city now, the airport is closed and business establishments are shut down. We are holed up in inside a hotel, and nobody is allowed in or out. We don't know what is happening. From time to time we see a group of military personnel passing in front of the hotel. We heard some loud bangs this morning; our colleague saw a street fighting on going. But from our point of view it is relatively peaceful.

I am a pilot based in N'djamena for a local operator. It's quiet at the moment and I have not heard any gunfire or shelling for over 30 minutes. The situation is very confused with both conflicting reports on national radio and the international reporters. The airport is still open and there has been no mass evacuation of expatriates to the best of my knowledge.
Mark Jefferies, N'djamena, Chad
What is happening in Chad is the result of the sit "tightism" that is plaguing African dictators: once in power they will only want to go at the call of the barrel of the gun. It aches me because this gives the western world, one more opportunity to mock at Africans as being uncivilized.
To solve the problem in Chad, Deby should go and the Chadian people vote an non-amendable constitution that limits Presidential mandates to two terms at most.
Aaron Agien Nyangkwe, Douala, Cameroon
Maroua is not far from the Chadian capital N'Djamena. We are now feeling the rebellion attack, which I condemn. The world should do something to stop any changing of power through gun or violence.
Azu Solomon, Maroua, Cameroon
I am not in N'djamena, but I have experienced what they are going through. Therefore, I wish to call on President Deby and rebel leader Nour to stop the fighting and start dialogue for the sake of their own people.
