At least 10 more insurgents have been killed in the city of Aleppo during clashes with Syrian government forces in the flashpoint city of Aleppo, the army says.
The Syrian army launched a major mop-up operation against the armed groups fighting against the government in Aleppo on Wednesday.
The army forces managed to retake control of Aleppo’s strategic district of Salahuddin and inflicted heavy losses on the insurgents.
Syrian troops also clashed with insurgents in Aleppo's Bab al-Nayrab district in the southeast, killing dozens of them.
Fighting continues between the Syrian Army and the insurgents in several other areas of Aleppo, including the northern neighborhood of Ashrafyiah, the southern district of Sokkari and the central area of Seif al-Dowla.
The Syrian army has also discovered a cache of missiles in a warehouse near Aleppo.
Foreign-backed armed groups have been conducting terrorist attacks in Aleppo since July 20 after they were defeated in the capital Damascus and were forced to flee.
Some reports suggest that anti-government insurgents operating in Aleppo may have been provided with chemical weapons. The insurgents have also acquired dozens of portable surface-to-air missiles.
Reports also say that the Turkish military supplied the militants with Stinger missiles during a brief incursion into Syrian soil on Tuesday.
Syria has been the scene of deadly unrest since mid-March 2011 and many people, including large numbers of army and security personnel, have been killed in the violence.
