A spokesman for the US-led coalition says the SDF has also captured around 10 sq km of territory from Daesh north of Raqqa during the past two days.
The US-backed SDF group on Tuesday claimed that it is on the verge of seizing full control of the southern neighbourhoods of Daesh-held Raqqa, the group said on Tuesday.
The US-led coalition said SDF advancing from the east were within 300 metres of meeting up with those advancing from the west. The SDF was making "consistent gains" every day, the coalition spokesman said.
The SDF launched its US-backed campaign to seize Raqqa in early June. The assault on Daesh's de facto capital in Syria overlapped with the campaign to drive the group from the Iraqi city of Mosul, where Daesh was defeated last month.
"There is a fierce resistance from Daesh, so we can't determine when exactly we'll take (full control). Around 90 percent of the southern neighbourhoods are liberated," said the SDF.

The SDF is dominated by YPG, which is the armed wing of the PYD. The PYD is the main partner for the US-led coalition against Daesh in Syria. Turkey is incensed by the US decision to arm the YPG/PYD as it considers the group as the Syrian branch of the PKK.
The PKK is recognised as a terrorist group by Turkey, the US and EU.
Daesh has lost large expanses of territory in Syria over the last year to separate campaigns waged by the SDF, the Russian-backed Syrian regime, and Turkey-backed Syrian opposition forces.
