CAMBRIDGE (CBS) – Family members of a Boston-based journalist trapped in Libya called for his immediate release on Thursday.

Relatives of James Foley gathered at the Memorial Church in Cambridge for a candlelight vigil.

Foley and another reporter, Clare Gillis have been imprisoned in Libya since last month.

Both were doing reports on the rebel uprising in Libya when pro-Moammar Gadhafi soldiers captured them.

We think it’s very important that people are aware that innocent journalists are being detained in Libya… more than a month now,” said mom Diane Foley.

Both the Gillis and Foley families have heard from the captured journalists and have been told they’re being treated well in captivity.
