In Sudan, more people have been displaced because of fighting than in any other conflict on Earth. Today, the UN Security Council has been meeting to discuss the situation in Sudan, with the UK calling for an immediate ceasefire as the country teeters on the brink of famine. As many as 5 million people faced starvation because of the war. But how did we get here? Well, back in 2019, the head of the Sudanese Army and the leader of a powerful rebel group, the Rapid Support Force forces took control of the country in a power-sharing agreement. But the men fell out and have been battling for total control for almost a year. Tens of thousands have died and millions have had to flee their homes. Now, the BBC hasn't been able to report from the front line since the fighting began. But now, the BBC Arabic's Feras Killani has gained rare access with the Sudanese Army in the city of Omdurman, close to the capital Khartoum. A warning, you may find and some of the details in his report upsetting.

Children in Sudan are facing a living nightmare. Aid agencies warn an entire generation is at risk. 300 families are crammed into this school here in Port Sudan. Zubaida, a mother of eight, has leukemia. She hasn't been able to get her medication since the war erupted last April.

My last pills finished three days before the war. From that moment on, I'm suffering. I'm in constant pain. I'm so tired.

These classrooms should be full of children learning. Instead, desperate people from across Sudan are sheltering here for safety. But there are horrible stories hidden here. Five people have died of cholera, and others are suffering from severe diseases. This clinic feels like a frontline of a humanitarian disaster the world doesn't know is happening. Starving children getting what little help they can. We meet Iqram, who has lost all hope, struggling to keep her three-year-old daughter, Monasek, alive. She could barely tell us the RS If she had a life, stole her home, stole her life. And this is where her life was, in the city of Omderman, the front line of this war. Sudanese army troops Website. The US have been in a battle with the rapid support forces for nearly a year. A war that has devastated this country. The UN says both sides face accusations of horrific abuses, even war crimes. Claims both deny. The army was keen to show us the damage they say was inflected to the city and its people by the RSF. They tightly controlled what we saw and where we went. Millions across the country have had to leave their lives behind.

Few have stayed 64-year-old Moukhtar took us to see what used to be a town square.

Now a makeshift brevia.

There are 150 people here. I knew many of them, Muhammad, Abdullah, Jalal. It's just me left.

A moment to remember their names. For money, a grave is only a number. The world has been distracted with other words, other suffering. But the appeal from here is clear. The world is being urge not to forget Sudan. Firaske, Lining BBC News, Sudan.

Well, Lisa Douzet, our Chief International Correspondent is here. We just heard the suggestion there that this is a conflict the world has forgotten. You were briefly in Sudan at the very beginning of the fighting. What diplomatic efforts are taking place to try to end all this?

A living nightmare that the world doesn't even know is happening is how Farris described it in that powerful report. But of course, Clive, the world does know what's happening, but world powers are distracted by bigger crises, they think, in Gaza, in Ukraine, and now in Haiti. It's dominating their attention and aid. Regional powers in Africa the Middle East certainly know what's happening. But different powers are backing different sides in this war, arming and empowering not just them, but their interests in a country which is mineral rich and on the Red Sea. Now, it is starting to change a bit. You mentioned in your introduction, a few days ago, the UN Security Council finally called for an immediate cessation of hostilities. Words matter, but it's going to take so much more than that. Pressure on these two warlords to come to the table, even to allow to reach the millions who desperately need it. Pressure on these warlords to be held accountable, both of them accused of war crimes, even genocide. Pressure, too, even to let journalists in to see what is happening on the ground. Until the world, world powers in the West and in the region speak more loudly and act more forcefully, Sudan will be forsaken.

Then if Sudan goes, so does stability in the Horn of Africa, in the Red Sea, and then the world will pay attention, but then it's too late.

Too late indeed. Okay, Lise, thank you. Lise Doucet, there.
