Aleppo was once a place of culture and commerce, with a jewel of an old city that was on Unesco's list of world heritage sites. Now, the five-year civil war that rages in Syria has left much of it destroyed and divided roughly in two, with President Bashar al-Assad's forces controlling the west and the rebels the east. A month ago, government forces re-imposed a siege on the east, and launched an all-out assault to take full control of the city, accompanied by an intense and sustained aerial bombardment. Activists say the offensive has left hundreds of civilians dead, but the government and its ally Russia have denied targeting them and blamed rebel fighters for operating in residential areas. But what about the more than 250,000 people who are trapped there? Where are they getting their food from? Do they have enough water and medicine?
The quality of daily life depends on where you live
There is no single group in charge in eastern Aleppo - it is divided between mainstream rebels backed by the US and its allies, the jihadist group Jabhat Fateh al-Sham, and Kurdish forces who say they support neither the government or the opposition. In the Kurdish-controlled district of Sheikh Maqsoud, markets are well stocked and prices are stable, according to the Reach Initiative, which is in touch with people on the ground to gather regular humanitarian reports. One road out of Sheikh Maqsoud has opened up in the daytime, allowing people to get out and goods to get in. But the district is surrounded by checkpoints, meaning people from the other areas under siege cannot get in and out easily. In other parts of eastern Aleppo, the situation is more urgent. Generators are running out of fuel, meaning electric power is sporadic, and some air raid shelters - where residents may spend hours or wait overnight for bombing to stop - are not wired with electric light at all.
Food and water have become weapons of war
Humanitarian aid agencies have been unable to get into eastern Aleppo since the siege resumed on 4 September. Both the United Nations and the International Committee of the Red Cross have been calling for humanitarian corridors to be opened up since then, but so far those calls have been ignored. That said, charities are still in contact with people who live there. Reach says some markets are still up and running in parts of Aleppo under siege, but for key foodstuffs like eggs, flour, vegetables, fruit, chicken and cooking oil, whether you will get them or not is touch-and-go. In three districts - Qadi Askar, Masakin Hanano and Tariq al-Bab - markets have run out of flour completely. Reach says some people are rationing their last pieces of dried bread and tubes of tomato paste, while others are bartering what is left in their cupboards. For food that you can get, the price is hugely inflated.
Before the conflict, seven pieces of flatbread cost 15 Syrian pounds. Now, it comes in packets of six pieces, costing 451 Syrian pounds on average (£1.66, $2.12) - expensive in a city under siege, where many ways of earning money have disappeared. Water, too, has become a weapon in the war as government forces attempt to make the rebels and civilians in eastern Aleppo surrender. Pumping stations have been damaged in the bombing and most of the city - including parts of the government-held west where some 1.2 million people live - has no running water coming out of the taps. People are buying water from wells and privately-owned water tankers, and carrying it home in buckets. Many have reported that it tastes bad, and there is no guarantee that it is free of disease. It is hard to say whether anyone has died of hunger in the siege because with aid agencies unable to get inside, they cannot accurately diagnose the level of malnutrition. But Pablo Marco from the charity Medecins Sans Frontieres (MSF) said: "The siege is pushing people towards starvation."
