Almost 40 migrants were intercepted off the Kent and Sussex coasts, trying to cross the English Channel, BBC reports.
Twenty people were found around Dungeness by Border Force officials, after arriving in a dinghy, on Saturday.
In a second incident the force's cutter intercepted a small boat in the Channel, and brought 11 men to Dover.
Another six migrants, including three children, were found by police on the Sussex coast.
All 37 migrants presented themselves as Iraqi and Iranian nationals.
At least 966 people, including about 89 children, have crossed the Channel in small boats since 3 November 2018.
