Protesters urged the Italian government to push more strongly for the release of Adjmal Naqshbandi and Rahmatullah Hanefi.
Naqshbandi, still in Taliban hands, was the interpreter of abducted Italian reporter Daniele Mastrogiacomo, who was released by the Taliban nearly two weeks ago.
The nongovernmental organization Emergency claims that Hanefi, the director of the group's hospital in the southern town of Lashkar-gah, was abducted on March 20 by Afghan secret services.
Hanefi, on behalf of the Italian government, had just helped negotiate Mastrogiacomo's release in exchange for five Taliban prisoners.
"Rahmatullah has done nothing wrong," Emergency founder Gino Strada told RFE/RL before today's rally. "He has done what Emergency has requested him to do, which was again requested to Emergency by the Italian government. And what he has done is basically to contact the Taliban and pass them a message for us for the liberation of these hostages."
The Milan-based NGO, which operates in war zones around the world, has three hospitals and nearly 30 first-aid posts in Afghanistan. It has threatened to curtail its work in Afghanistan if Hanefi is not released.
The Afghan Interior Ministry has yet to respond to RFE/RL inquiries.
