Six people have died after a boat carrying migrants sank in the Channel, off the French coast, reports BBC News.
Two people may still be missing, a spokeswoman from French coastal authority Premar said, after the vessel got into difficulty in the sea near Calais in the early hours of Saturday.
About 58 people were rescued by British and French coastguards, officials said.
A number of people were seen being brought off a lifeboat, some on stretchers, in Dover.
The extent of injuries remain unclear and the exact numbers of those rescued have changed since the morning as more information was released.
The six people who died were Afghan men thought to be in their 30s, the AFP news agency reported Philippe Sabatier, deputy public prosecutor for the French coastal city of Boulogne, as saying.
He said those rescued included some children and were mostly from Afghanistan, although there were some Sudanese.
French authorities said a passing ship first raised the alarm that an overloaded boat was in difficulty off the coast of Sangatte.
When the French lifeboat arrived, they found people in the sea, with some screaming for help.
The Dover lifeboat, which was already in the Channel dealing with another boat carrying migrants, joined the rescue operation.
One of the volunteer rescuers told the Reuters news agency migrants were using shoes to bail water out of the sinking boat.
Anne Thorel said there had been "too many" people on board.
Another French rescuer, Jean-Pierre Finot, said: "Some were suffering from sea sickness and the boats are quite simply overloaded... [and] can no longer move forward".
Rescue crews say this is the seventh time this week that they have had to pull people from the water, raising concerns that the smugglers organising the crossings may be using a defective batch of boats.
