STORY: Essentials like bread were in short supply in Aleppo in the days after Islamist rebels took control of the northwestern Syrian city from government forces.

Reuters visited Aleppo Wednesday and spoke to locals lining up for food and fuel.

While a week on, some services are back - including some set up by the rebels...

Ahmed Hamdan said some people were not able to get bread at all.

"In terms of the bread situation, there is a very, very big crisis. People in their hundreds are at the bakeries. Some people can get brea and others not - at this time. The bread situation - some good people gave us bread. Bread has become a struggle."

The insurgents, led by the group Hayat Tahrir al-Sham, are trying to show Syrians and the West that they are a viable alternative to President Bashar al-Assad.

They've set up several services like traffic control, and lifted a curfew.

However, gas remains in short supply.

One motorist complained prices were too high - it's profiting those in power, he says.

HTS is still seen as a terror group by Turkey and the West, even though it cut ties with al Qaeda and rebranded itself as a more moderate group.

A decade ago, Aleppo was a major battle site between al-Assad's government and rebel forces - a bloody civil war that had no formal end and which killed hundreds of thousands of Syrians, and displaced millions.

But in the past week, the insurgents led by HTS staged a whirlwind advance in the north of the country.

They captured Aleppo last week and Hama on Thursday, which lies more than a third of the way between Aleppo and Damascus, Syria's capital in the south.

The onslaught is President al-Assad's biggest challenge in years, and a devastating blow to him and his Russian and Iranian allies.
