More than 70 countries signed on Thursday a letter urging the UN Security Council to prevent the Syrian army from conducting indiscriminate air strikes across Syria.
The letter, written to UN Secretary General, the Security Council and General Assembly criticised the use of barrel bombs and the violence against civilians.
"Tragically, these barrel bomb attacks in Aleppo were the latest in a long line of the grisly and horrific use of aerial weapons, including barrel bombs, that have been launched by the Syrian Air Force on crowded urban areas, such as markets and bakery queues, hospitals and medical facilities, schools and places of worship, transportation hubs and residential buildings, throughout the course of the Syrian crisis leaving thousands dead," the letter said.
Supported by 71 signatories, the letter urged the Security Council to implement last year’s resolution aimed at delivering humanitarian aid and ending civilian killings.
While the United States, Britain, and France signed the letter, Russia and China didn’t approve the drafting of the letter.
Syrian regime has recently intensified aerial attacks on the towns held by the Syrian opposition forces near Aleppo, as fierce battles take place between ISIS militants and Syrian rebels in the eastern and northern countryside of the province.
Separately, a US-led coalition has been targeting ISIS in Syria since September. Human rights groups have estimated hundreds of civilians have been killed in coalition air strikes.
More than 220,000 people have been killed in Syria since the anti-government protests began in March 2011. More than 7.6 million Syrians have fled the country while hundreds of thousands are displaced internally.
The UN estimates around 12 million are in need of humanitarian aid throughout Syria.
