The French police are conducting a large operation in the English Channel after failed attempts to cross.
There were several attempts launched to cross the Channel this morning from the French coast.
Local media is reporting that five people have died, and there are "several lifeless bodies" in the water.
Our Europe correspondent Adam Parsons, reporting live from the Dunkirk on the northern coast of France, says this is a "really serious incident".
He says there are four coastguard and French naval vessels that are "clearly assisting with what is evidently a major operation".
Adam explains that the conditions are currently "perfect for launching these [small] boats", but he emphasises that they are "invariably ill-suited to crossing this very busy maritime crossing".
