A mass cull of poultry has been ordered after an outbreak of bird flu on a farm in Yorkshire.

A 3km protection zone and 10km surveillance zone have been put in place around the farm near Hornsea in the East Riding of Yorkshire and all the fowl on the property will be destroyed, the Department for Environment, Food and Rural Affairs (DEFRA) said.

The discovery of the H5N5 variant of highly pathogenic avian influenza (HPAI) on the farm means DEFRA has increased the risk warning for wild birds “from medium to high”.

The virus is typically spread through birds’ faeces, mucus and saliva.

“All bird keepers are urged to remain vigilant and take action to protect their birds following a further increase in the avian influenza (‘bird flu’) risk levels in Great Britain,” DEFRA said in a statement.

Bird flu may be evolving under the radar

Bird flu has killed hundreds of millions of birds around the globe in recent years, and has increasingly spread to mammals, raising concerns it may lead to human-to-human transmission.

The last avian flu outbreak in the UK happened in February and was described as the country’s largest ever.

That was the H5N1 strain, while the latest outbreak in Hornsea is the H5N5 strain.

In July, US scientists said their was “strong evidence” bird flu has spread from mammals to humans for the first time, marking another step in the evolution of the deadly virus.

Analysis concluded a Texas farm worker who tested positive for the H5N1 virus caught it from sick dairy cattle.

Although there have been other people infected with the virus in recent years – including some who have died – they all acquired it from birds.

Large groups of youths have been throwing fireworks, bricks and bottles at police in Edinburgh, during a night of disorder across the city.

Video posted online shows officers responding to Bonfire Night incidents in the Sighthill, Niddrie, Gracemount and Gilmerton areas.

Riot police have been seen on the streets of Edinburgh, wearing helmets and carrying shields, as fireworks were lit and exploded around them.

Footage from Gilmerton, a suburb in the southeast of the city, also showed burning debris in the street as youths rode on bicycles.

Police were given extra stop and search powers in certain areas following “intelligence” about planned disorder and firework-related crime.

Superintendent Neil Wilson said: “We are currently responding to incidents of disorder involving large groups of youths throwing a range of objects, including fireworks, bricks and bottles, across Edinburgh.”

A helicopter was also deployed as part of Operation Moonbeam, aimed at supporting local police in tackling fireworks-related offences.

Meanwhile Lothian Buses withdrew all services from the Niddrie area for safety reasons.

Niddrie was also the scene of disorder on 31 October, when police and public transport vehicles were pelted with fireworks and bricks.

On Tuesday, officers in Glasgow seized a “significant quantity” of fireworks from a van in the Drumchapel area which it is alleged were being “sold to the general public, including children”.
