Syria state TV says 50 hurt in rebel poison gas attack

DAMASCUS, Syria. — At least 50 civilians were being treated Saturday following a suspected poison gas attack by Syrian rebel groups on the government-held Aleppo city in the country's north, according to reports in Syrian state media.

Most of those admitted to hospitals had breathing problems and blurred vision, doctors told state TV.

There was a stench of gas in Aleppo city after projectiles were fired, said Rami Abdurrahman, the head of Britain-based Syrian Observatory for Human Rights.

Rebel commanders and opposition figures denied they lobbed gas into Aleppo and accused Damascus of seeking to undermine an existing ceasefire. Earlier Saturday, government shelling of a rebel-held area in neighboring Idlib province killed at least seven civilians.
