Armenia's parliament descended into a mass brawl as the country remains split following last year's defeat in the war with Azerbaijan for control of Nagorno-Karabakh.

Prime Minister Nikol Pashinyan had faced a backlash at home over a peace deal with Azerbaijan which saw Armenia cede swathes of territory it had controlled for decades.

In June, Mr Pashinyan's party secured a landslide victory in the snap polls he called after months of protests and mounting discontent.

The newly-formed parliament, however, has struggled to find common ground as Mr Pashinyan's supporters and the opposition traded blame over the loss of Karabakh.

Members of the opposition starting throwing bottles of water at a speaker from Mr Pashinyan's Civil Contract party during a parliament session.

The incident sparked a brawl, forcing the parliament's speaker to pause the session and call in security.

Water bottles and hand sanitisers have since been removed from the chamber.

After the session resumed, another brawl broke out when an opposition deputy was interrupted by heckling.

A member of Mr Pashinyan's party then tried to kick the opposition politician, sparking mass fighting on the chamber's floor.

Several members of parliament were removed by security and one politician ended up in hospital with an eye injury.

A day earlier, another opposition deputy was removed from the chamber after she called Mr Pashinyan's party "supporters of the capitulator".

Armenia has been in political crisis since the defeat in the six-week war over disputed Nagorno-Karabakh last autumn that claimed around 6,500 lives.

The fighting ended with a Russian-brokered ceasefire that saw Azerbaijan take control of parts of Karabakh and surrounding districts which Armenian forces controlled since 1994.

Russia has deployed peacekeepers in the area to oversee the ceasefire it mediated to end the fighting.

Both Azerbaijan and Armenia have reported occasional shootouts in recent months along their shared border, sparking fears of a flare up in the territorial dispute.
