MILAN, July 6 (Reuters) - A migrant rescue boat docked at the port of Lampedusa on Saturday in defiance of a ban on entering Italian waters, the second NGO vessel to clash with Italian authorities in a week.
The vessel Alex, carrying a number of migrants, declined a Maltese offer to go to Malta, as the Mediterranea NGO operating it said such a long journey would have been dangerous for the people aboard.
The boat docked at the same quay where a week ago another NGO vessel collided with an Italian police boat after deciding to let migrants disembark after two weeks in international waters. (Reporting by Valentina Za, Editing by William Maclean)
