Around 1,000 people reached Britain in a single day after risking their lives in small boats in the English Channel, a new record for the current crisis.
A young girl wrapped in a red jacket was seen being carried ashore in Dover on Thursday, one of hundreds of people brought into the Kent port after being picked up at sea.
Lifeboat crews and Border Force boats were busy well into the evening after spending hours intercepting boats in the Dover Straight throughout the day.
Thursday's total will surpass the previous single-day record for the current crisis of 853 set earlier this month when figures are finalized.
It comes despite two people losing their lives attempting the perilous crossing and more feared missing at sea in recent weeks.
Border officials were busy well into Thursday evening in Dover as they worked to process the many arrivals.

At least 100,907 people have arrived in Europe via the Mediterranean by land and sea so far this year, according to data from the United Nations High Commissioner for Refugees (UNHCR).
At least 1,313 people are estimated to be dead or missing, according to the same data.
