The US-backed Syrian Democratic Forces (SDF) are on the verge of seizing full control of the southern neighborhoods of Isis-held Raqqa, a Kurdish official said on Tuesday.

The US-led coalition said SDF fighters advancing from the east were within 300 metres (330 yards) of meeting up with those advancing from the west. The SDF was making “consistent gains” every day, the coalition spokesperson said.

On Monday, the World Health Organisation (WHO) said there were critical shortages of medical supplies in Raqqa, where it estimated up to 50,000 civilians remained. Separately, Medecins Sans Frontieres said many sick and wounded people were trapped.

The SDF launched its US-backed campaign to seize Raqqa in early June. The assault on Islamic State's de facto capital in Syria overlapped with the campaign to drive Isis from the Iraqi city of Mosul, where Isis was defeated last month.

The Kurdish official told Reuters SDF fighters advancing from the east and the west remain separated by a few streets where fighting continued.

Full control of the southern districts would sever Isis's last remaining path to the Euphrates River which is to the south of the city.

“There is a fierce resistance from Daesh, so we can't determine when exactly we'll take (full control),” said the official, referring to Isis. “Around 90 per cent of the southern neighborhoods are liberated,” the official added.

The spokesperson for the US-led coalition said SDF fighters had also captured around 10 square km (four sq miles) of territory from Isis north of Raqqa in the last two days.
