People are feared to have died after a small migrant boat ran into difficulties in the early hours in the English Channel near Kent.
The BBC’s Simon Jones said it was understood there had been deaths but authorities have not confirmed them.

The coastguard, the French Navy and an air ambulance were sent to help.
A fishing boat, which was also in the area, helped with the rescue.
HM Coastguard helicopters from Lydd and Lee on Solent were also involved.
