Turkey and the United States lashed out against the Syrian regime after the death toll from a missile strike on Aleppo rose to 58, while a French photographer wounded in the conflict was confirmed dead on Sunday.
On a visit to the United Arab Emirates, Turkey's Prime Minister Recep Tayyip Erdogan condemned the Assad regime saying there to be large number of women and children casualties.
He vowed that his country will not be silenced over the crimes the regime is committing towards its people.
Erdogan's statement came as the French foreign ministry confirmed that freelance photographer Olivier Voisin, who was seriously wounded in Syria on Thursday, died of his wounds after surgery in Turkey.
Turkey's southern neighbor has been locked in a 23-months-long conflict in which the United Nations estimates over 70,000 people have been killed.
The Syrian Observatory for Human Rights said on Sunday, at least 70 people were killed in violence across the country.
Late Sunday, the Free Syrian Army reported to have launched attacks on Aleppo International Airport, the second largest airport in the country after Aleppo’s massacre caused by Scud missiles on Saturday killing at least 29.
Fierce fighting erupted during the night on the Syria-Lebanon border between Syrian troops and unknown gunmen, leaving a Lebanese man dead and four wounded.
This comes as Lebanese President Michel Sleiman demanded Syria "refrain from firing towards Lebanese territory."
The violence was triggered by the death hours earlier of another Lebanese man, who was killed on Saturday in gunfire coming from the Syria side of the border near a river separating the two countries, the security source said.
Early in the revolt against President Bashar al-Assad's regime, Turkey broke ties with Damascus and led international calls for his ouster.
Ankara has since backed the uprising against Assad by offering shelter to defectors from Assad's army and hosting opposition meetings, while some 200,000 Syrian refugees have fled to Turkey, many of them living in squalid camps.
On February 15, Assad's government sent a letter to the United Nations blasting Turkey's "destructive" role in the Syrian conflict.
Damascus has systematically blamed foreign powers, key among them Turkey, the West and Gulf countries, for the war in Syria.
