An ultra-right Hungarian mayor has issued a chilling video discouraging refugees from entering the country.

László Toroczkai, the mayor of Ásotthalom on the Hungarian border with Serbia, warned migrants not to enter his town in the dramatic film.

But he was quickly mocked online for his slick 'action movie' with one comparing it to the Jurassic World movie.

The bizarre footage and anti-immigration video includes a choreographed chase on horseback

The 'action movie' also has an aerial shot of a car and motorbike travelling along the border

As dramatic music plays in the background, a helicopter is also filmed in a chilling warning to refugees

In the intimidating film, the mayor begins by speaking directly into the camera with his warning message.

Action-movie style music is then played in the background as a simulated chase sequence filmed from the air - featuring a motorbike, a helicopter and two thick-set men on horseback - takes place.

Migrants are told they will be arrested and could face prison if they are caught trying to enter the country illegally.

The bizarre footage closes with Toroczkai standing in a field wearing Terminator-style shades, surrounded by burly border guards in camouflage as the music ends.

He then uses Google Maps to show how the land route from Serbia to Germany is longer through Hungary than Croatia and Slovenia.

He finishes by saying: 'Do not trust lying human traffickers. Hungary is a bad choice. Asotthalom is the worst.'

After the extraordinary video was uploaded to social media, it was widely mocked by those on the opposite end of the political spectrum - with some replacing various parts of the footage with scenes from the Jurassic World movie.

Toroczkai is a leader of the far-right 64 Counties Youth Movement in Hungary that advocates the revision of the Trianon Treaty of 1920, which defined the current borders of the Hungarian state.

In 2004, he was banned from Serbia for one year because of a fight in the town of Palić.

Two years later, the authorities of Slovakia also banned him from the country for five years because of demonstrations he organised in front of the Slovakian Ministry of Internal Affairs.

The video comes just days after Hungary closed its entire border with Serbia after making it illegal to enter the country or damage the border fence.

The country's courts have started fast-track trials of arrested migrants.

This led to ugly clashes at the Hungarian-Serbia border on Wednesday, as hundreds tried to breach a razor-wire fence.

Heavy-handed Hungarian police fired tear gas and water cannon to force migrants back from its border.

This has forced Serbia to move migrants towards Croatia, which has inflamed tensions between the countries who say they are at breaking point.
