Britain will not become a "safe haven" for migrants in Calais, David Cameron has warned, after hundreds continued their attempts to reach the U.K.
The prime minister warned illegal immigrants would be removed from the U.K., as migrants told the BBC they remained determined to reach Britain.
Cameron was speaking after people gathered for a third night at fencing at the Channel Tunnel freight terminal. More than 3,500 people have tried to get into the tunnel terminal this week.
Several hundred migrants were escorted away from the terminal by French police on Wednesday night - the third night of large-scale attempts to storm the terminal.
The fresh attempts came despite the death of a man, believed to be a Sudanese national and aged between 25 and 30, who was crushed by a lorry on Tuesday.
Nine people have been killed attempting to cross the Channel in the past month.
The prime minister said the situation was "very testing" because there was a "swarm of people coming across the Mediterranean, seeking a better life".
The Refugee Council attacked Cameron's use of the word "swarm" as "irresponsible, dehumanising language".
