MYTILENE, Greece (AP) — Two dozen Greek and foreign aid workers and volunteers who participated in migrant rescue operations on an eastern Greek island have gone on trial in a smuggling-related case that’s been widely criticized by human rights groups.

The 24 defendants deny all the charges, saying they did nothing more than help rescue people whose lives were in danger. The trial in the town of Mytilene on Lesbos began Tuesday and was adjourned until Friday.
