Paris, Sep 3 (AP) A boat sank off France's northern coast and plunged more than 50 migrants into the waters of the English Channel as they tried to cross it on Tuesday, and French maritime authorities said around a dozen people were recovered in critical condition.

The English Channel is a busy and often treacherous waterway. At least 30 migrants have died or gone missing while trying to cross to the UK this year, according to the International Organisation for Migration.
