(presstv) -- At least 45 people have been killed in the US’ latest airstrike in Syria.

According to local sources on Monday, the civilians were killed after US’ jets targeted the al-Touse’eiyah district in the city of Raqqah.  

The incident comes just one day after the so-called Syrian Observatory for Human Rights reported that more than 3,000 people, including nearly 1,000 civilians, have been killed during the past month.

The US-led coalition has been conducting airstrikes against what are said to be Isis targets inside Syria since September 2014 without any authorization from the Damascus government or a UN mandate. 

The military alliance has repeatedly been accused of targeting and killing civilians. It has also been largely incapable of achieving its declared goal of destroying Isis.

 The Syrian Ministry of Foreign Affairs and Expatriates, in two separate letters sent to UN Secretary General António Guterres and rotating President of the UN Security Council Amr Abdellatif Aboulatta on August 24, stated that the US-led coalition was perpetrating war crimes and crimes against humanity through aerial bombardment of residential neighborhoods.
