Syrian troops reached the edge of the northern province of Raqqa on Friday, home to the de facto capital of the Islamic State group’s self-styled caliphate, in a push that leaves the extremists fighting fierce battles on four fronts in Syria and neighboring Iraq.
ISIS, which controls large swaths of territory in both countries, is fighting Syrian troops, US-backed fighters and opposition militants in northern Syria and is facing an offensive by Iraqi forces on their stronghold of Fallujah.
The Syrian Government has had no presence in Raqqa since August 2014, when ISIS captured the Tabqa air base and killed scores of Government soldiers. The provincial capital, Raqqa, became the militants’ first city.
The Britain-based Syrian Observatory for Human Rights said Syrian troops reached the "administrative border" of Raqqa province under the cover of Russian airstrikes. It said that during three days of fighting 26 IS fighters and nine troops and pro-government gunmen were killed.
The media arm of lebanon's Hezbollah group, which is fighting alongside Government forces, said Syrian troops reached the border of Raqqa province after advancing about six kilometers this afternoon. The front line is around 80 kilometers from the city of Raqqa.
Syrian troops began their advance toward the province Wednesday, the same day that US-backed forces launched an attack on the ISIS-stronghold of Manbij, some 115 kilometers to the northwest of Raqqa. It is unclear if the attacks were coordinated.
The US-backed predominantly Kurdish Syria Democratic Forces advanced closer to Manbij, which lies on a key supply route linking the Turkish border to the city of Raqqa, on Friday.
The Observatory said SDF fighters had captured 34 villages near Manbij. Another activist group, the local Coordination Committees, said the fighting is now concentrated on the south of the town.
