MILAN -- The Latest on Europe's response to mass migration (all times local):
French authorities say 21 migrants have been rescued while trying to reach Britain by crossing the English Channel in small boats.
A regional maritime authority said in a statement Tuesday that a helicopter and coast guard ship retrieved nine migrants from a boat with a dead engine in waters off Calais.
A separate operation rescued 12 migrants, including two children, from another boat off Boulogne-sur-Mer.
The statement says two passengers had mild hypothermia, and all were brought back to France.
Under British pressure, French authorities stepped up efforts to stop Channel crossings by migrants after a surge in attempted trips on one of the world's busiest maritime traffic routes.

The German humanitarian group Sea-Eye says drinking water and food is running low onboard its rescue vessel at sea for the sixth day carrying 64 migrants, as Europe haggles over where to provide a safe port.
Sea-Eye said Tuesday that it has informed Malta, the nearest port, of the scarcity of food and water for the migrants, including 12 women, a child and an infant.
The European Union, meanwhile, said it had triggered talks with member states to identify a port and countries to take in the migrants, as the nearest countries, Malta and Italy, have refused to allow port access to any NGO rescue ship.
Sea-Eye spokesman Dominik Reisinger said the "political question about the distribution of the rescued ... overshadows the human rights" of those on board.
