The Syrian army on Tuesday denied involvement in a suspected chemical attack that left dozens of people dead in an opposition-held town in the country's northwest.

"The army command categorically denies using any chemical or toxic substance in Khan Sheikhun today," said a statement carried by the state news agency SANA.

"It stresses that it has never used them, any time, anywhere, and will not do so in the future," it added.
