(CNN) -- Syrian government forces launched airstrikes Sunday
on the rebel-held city of Qusayr in Homs province, the opposition said.
The offensive comes after months
of fighting on the outskirts of the city, said Abu Ali, an opposition
spokesman.
Syrian state television confirmed
that an assault is under way.
"The Syrian Army has tightened
its siege on terrorists and is attacking their headquarters in the southern part
of Qusayr," state media reported.
The city has been under rebel
control for months.
The opposition also accused
Hezbollah fighters from neighboring Lebanon of joining Syrians government troops
in the assault, a claim the government of Bashar al-Assad has disputed in the
past.
