AROUND 200 people - including school children - are reported to have been poisoned in a chemical leak just outside Moscow.

More than 20 kids have been hospitalised after a possible hydrogen sulphide leak at the nearby Yadrovo dump, Russia's TASS news agency reported.

5 Locals in Volokolamsk, near Moscow, are believed to have been poisoned by a chemical leak from the nearby Yadrovo landfill

Footage from Volokolamsk, home to just 23,000 people, shows hundreds of people queuing for treatment outside the local hospital.

They were all reported to be suffering from the same symptoms - dizziness and nausea.

A local source told TASS: "The teachers noticed the children began to feel unwell and immediately called the hospital."

Local education chief Ekaterina Volkova later revealed the symptoms were a result of a suspected hydrogen sulphide leak.

Earlier this month, riot police were called in to disperse protesters from Volokolamsk who complained their town was being polluted by noxious gases.

Demonstrators blocked a road leading to the Yadrovo landfill on March 8 and prevented rubbish trucks from entering the town.

Volokolamsk police said around nine protesters were briefly arrested before they were released without charge, Radio Free Europe reported.

That protest came just one day after local officials announced a state of emergency after the level of hydrogen sulphide in the air was recorded at more than twice the normal level.

They said it was caused by a leak at the local landfill but the region's environment minister, Aleksandr Kogan, is reported to have said it wasn't harmful to locals.

Around 5,000 protesters also gathered in Volokolamsk to demand the landfill be closed on March 3.
