A hospital, school, blood bank and a bakery in Syria's rebel-held province of Idlib have been recently targeted by government forces, according to an Amnesty International report.
The organisation says it has verified six attacks in the past month that have displaced thousands of people to cities and towns close to the Turkish border.
"The Syrian government, with the support of Russia, is clearly resorting to the same unlawful military tactics which led to massive displacement, in some cases forced displacement," Amnesty said in a statement.
Amnesty based its report on witness testimonies backed up by "analysis of videos, open source information and satellite imagery".
"Deliberate attacks on civilians and on civilian objects, including hospitals and other medical facilities, and indiscriminate attacks that kill or injure civilians are war crimes," said Lynn Maalouf, Middle East Research Director, at Amnesty International.
On 26 March, Syrian government forces fired rockets at a school, east of Idlib city, during school hours.
Two staff members in a field hospital told Amnesty that a ten-year-old boy was killed in the attack and two other boys aged nine and ten were injured.
A resident went to the school immediately after it was hit.
"One of the rockets landed in the school playground. It seems there were kids playing then. Three were injured. One of them died. I saw the blood and the crater," the person told Amnesty.
Idlib is the last major opposition stronghold in north-west Syria. The province’s population has increased from one million to an estimated three million because of displacement from other parts of the country.
Eight years after the war started, more than 370,000 people have been killed. Syrian government forces control almost two-thirds of the country.
The United States recently accused Russia and the Syrian government of being responsible for "escalating violence" in Idlib.
"Despite Russia's claims to be targeting terrorists, these operations have caused dozens of civilian casualties and have targeted first responders as they attempt to save lives on the ground," a State Department spokesman said.
A Turkish-Russian deal was struck in September to stave off a planned regime assault that aid groups feared could spark the Syrian conflict's worst humanitarian crisis to date.
The offensive has been held off but the deal's provisions have not been implemented.
