At least one protester was hit by live ammunition on Monday in Hong Kong, after police opened fire and chaos erupted during mass demonstrations.
Local media in Hong Kong reported that the incident had taken place in the eastern side of the island.
Video footage showed a scuffle between black-clad protesters and a police officer, who moments later shot one of the protesters at close range. The protester was then seen lying in a pool of blood with his eyes wide open.
Authorities have not yet commented on the incident.
Riot police were deployed on Monday ahead of the demonstrations. Services on some train and subway lines were disrupted. Protesters were seen using barricades to block roads across Hong Kong.

Pro-democracy activist Joshua Wong said on Twitter that a fierce crackdown had begun early in the day and showed footage of clashes between police and protesters.
"Barely 9 o'clock in the morning, and across the other side of town, in Kwai Fong, a traffic cop gone berserk on a motorcycle is running protesters over," Wong wrote.
The violence comes just a week after a student died in hospital after falling from a building, when protesters were being dispersed by police.
Hong Kong has been rocked by protests since June, when residents took to the street to reject an extradition treaty with China.
Since then, the movement has snowballed into larger pro-democracy demonstrations that have been repressed by security forces. Protesters have taken a strong stance against police brutality and China's influence over the territory.
