Israel is seeking to deport pro-Palestinian activists who were detained and brought to shore when their Gaza-bound boat was intercepted by the navy, a legal aid centre advising them said on Sunday. The 21 activists from 10 countries were taken into custody late Saturday when the Handala was boarded in international waters as it attempted to breach an Israeli maritime blockade of the Palestinian territory.

The group also posted a number of videos with crew members urging people around the world to put pressure on their respective governments to "sanction" Israel.
