This is the astonishing moment around 50 migrants land on a packed beach and sprint up the sand as stunned tourists look on.

Footage taken by holidaymakers and posted on Twitter showed the Africans jumping off their rickety wooden boat as it reaches the shoreline as a father on the beach moves his children out of the way and two men interrupt a game of beach tennis.

Other tourists strolling along the water's edge as the cramped vessel reaches dry land can be seen breaking into a run to join crowds milling around a woman migrant who was injured in the mass arrival and is laid on her back on the sand.

The extraordinary scenes occurred at midday on Saturday at a beach in Zahora in the province of Cadiz, near to the headland of Cape Trafalgar close to where Horatio Nelson defeated Napoleon's combined Spanish and French fleet.

Dozens of migrants could be seen piling out of the boat as they reached the shore in the popular Spanish resort

This latest incident took place at the town of Zahora in Cadiz, just 40 miles away from the scene of another beach invasion on Friday in Tarifa

It happened a day after dozens of migrants were filmed storming a beach in Tarifa further east, but at 1pm and on a beach which at the time was much busier with tourists and locals than the one in Tarifa.

Witnesses told how many of the migrants ended up asking beachgoers for food and water after distancing themselves from the boat they had arrived on, known as a patera in Spanish.

Lorenzo Amor, president of Spain's National Federation of Self-Employed Workers who was on the beach at the time, tweeted: 'Arrival of a new patera on the coast of Cadiz.

'Right now at Zahora beach next to the Trafalgar lighthouse.

'The people inside the boat asking sunbathers who are on the beach for food.'

Only one of the migrants, the woman filmed lying on the sand, needed medical attention. She is said to have hurt her arm although not seriously.

The whereabouts of the others seen racing away from the boat was not immediately clear on Sunday.

The incident came on a day in which coastguards said they had rescued 284 people in more than a dozen boats in the Straits of Gibraltar, the point where the distance between Spain and Gibraltar narrows to just over nine miles.

Officials in Andalucia said a sports hall in Los Barrios near to the southern port of Algeciras - with space for 800 migrants - had been set aside.

Algeciras town hall said it was making water available to them and local supermarkets were providing milk, juice and biscuits.

The inter-governmental organisation International Organisation for Migration said the number of migrants and refugees reaching Spain through the increasingly-popular western Mediterranean route could soon exceed last year's figure for the whole of last year.

Spain has overtaken Italy as the preferred destination for migrant arrivals in Europe this year after Italy's new hardline Interior Minister Matteo Salvini introduced a blanket ban on migrant boats entering the country's ports.

The number of migrants and refugees using the western Mediterranean route to reach Spain stands at 20,992 between January 1 and July 25 according to the IOM, close to the 22,108 people who used it during the whole of last year.

Jose Ignacio Landaluce, mayor of Algeciras where many of the new arrivals come ashore, said last week his city risked becoming the new Lampedusa, the Italian island which has been overrun with migrants.

Spain's Interior Minister Fernando Grande Marlaska has tried to play down fears of collapse by insisting during a visit to the area on Saturday that the situation was 'exceptional' but under control and calling on a 'European solution' for a European problem.

Moroccan migrants are seen on a dinghy as they cross the Strait of Gibraltar sailing from the coast of Morocco before disembarking at 'Del Canuelo' beach in Tarifa on Friday

A boat from the Spanish Guarda Civil had tried to intercept the dinghy while it was still in the water, but the migrants sped off and fled from the authorities
