A 'HUGE' blast has rocked Hungarian capital Budapest just yards from a packed nightclub.

Two police officers are reported to be injured after the suspected gas explosion, but local reports have not yet confirmed the exact nature of the blast.

Early reports pointed to the cause being a gas explosion from a shop in the city centre.

Videos from the scene show dozens of police vehicles as hundreds of locals move away from the area.

Police confirmed in a statement on Sunday that two officers were injured by the blast - which is reported to have taken place near the Oktogon intersection in Pest at 10:30pm local time.

"The police have involved experts for the review of the area, interviewing witnesses and collecting data," the statement said.

"The local and expert examination of the origins of the explosion and the review of the damage is under way."

A government spokesperson declined further comment on whether the explosion had anything to do with a deliberate attack.

Hungarian Prime Minister Viktor Orban has been a vocal opponent of immigration into Europe and has campaigned for a referendum about migrant resettlement quotas on the premise that immigration increases the terror threat in Europe.

In a campaign leaflet to reject the quotas, Orban cited the Paris attacks last autumn and the Brussels and Nice attacks to underscore the perceived links between immigration and terrorism.

Hungary has seen merely a trickle of migration since it sealed its southern border with Serbia with a razor wire fence last year.

Police cordoned off a wide area around the Oktogon square in central Budapest and told residents to leave the buildings nearest the blast, local media reported. The normally busy intersection was packed with eye witnesses, including tourists.

A witness, Owain Brown, told the Mirror he saw at least five bodies lying on the floor "motionless."

He said: "Hopefully they were in shock or something.

"There is no building damage or cars outside damaged. Just glass from an apartment block."

"I am here on holiday and I was here in the hostel across the corner, and I was getting ready for a party," Polish tourist Olivia Sehildt said.

"Suddenly I heard a big boom...I was looking through the window and I saw a lot of cars coming, police, firemen, and a lot of people coming to the street...the windows were broken and nobody knew what happened."

Officials later confirmed two were injured in the explosion and taken to hospital.

Residents have been told to leave the building nearest the blast.

The scene had since been deemed safe by officials.
