The Kremlin on Monday rejected a report from New York-based Human Rights Watch which suggested its warplanes in Syria may have killed 59 civilians, including 33 children, as a probable media hoax.

The rights group cited local residents in northern Homs on Sunday as making the allegations, saying the Russian government should investigate the reports.

Dmitry Peskov, a Kremlin spokesman, dismissed the report.

"I think that this report is probably one of those."
