Russian officials have rebuffed claims that warplanes from the country struck a hospital in northern Syria.
Dmitry Peskov, a spokesman for president Vladimir Putin, told reporters this was another case of those who make such accusations against Russia being unable to back up their claims.
He added they should rely on official announcements from the Syrian government.
The Britain-based Syrian Observatory for Human Rights said Russian warplanes targeted the hospital in Idlib province, destroying it and killing nine people.
On Monday night, France’s new foreign minister said attacks like the one on the hospital “could constitute war crimes”.
