Anti-IS Syria force launches new phase in Raqa campaign
US-backed Kurdish and Arab fighters announced on Saturday a new phase in their campaign for the Islamic State group's Syrian stronghold of Raqa, but said they needed more weapons to win.
The Syrian Democratic Forces launched their campaign to capture the city last November and have taken some ground further up the Euphrates Valley but are still some distance away.
The SDF "announce the beginning of the third phase to liberate Raqa and its surroundings, which will target the eastern part of the province," spokeswoman Jihan Sheikh Ahmed said.
Speaking in the village of Aaliyah, north of the city, Ahmed said 750 more Arab fighters had joined the SDF after being trained by the US-led coalition.
The coalition has carried out air strikes against IS in Syria and Iraq since 2014.
Washington has dispatched about 500 troops -- including bomb disposal experts, trainers and special operations troops -- to support the SDF's campaign.
In a first, Washington has also provided the SDF with armoured sports utility vehicles since President Donald Trump took office, Pentagon and alliance officials said last week.
"Coalition forces provided our Arab contingent with vehicles, but the numbers are very small and we hope they will increase in the coming days," SDF spokesman Talal Sello said on Saturday.
Local SDF commander Rojda Felat said additional equipment that had been requested was not arriving quickly enough.
"The weapons that we need to liberate Raqa are tanks, Dushkas (heavy machine guns) and armoured vehicles," Felat, 38, told AFP.
"There has been a delay in the arrival of weapons we need, but the support will be increased in the next phases," she said.
Felat could give no timeline for when the SDF would reach the outskirts of Raqa, but said: "In this phase, we will get closer."
Of the roughly 30,000 fighters within the alliance, around two-thirds belong to the Kurdish People's Protection Units (YPG), which Turkey considers a "terrorist" group.
Washington insists it only delivers military aid to the Arab component of the SDF, but the assistance has still angered Ankara.
The SDF offensive is one of three rival operations targeting IS in Syria.
Further west, the jihadists are under attack in the city of Al-Bab, with Turkish-backed rebels on its northern outskirts and Syrian government forces now six kilometres (four miles) to the south.
