CARACAS, Venezuela (AP) — Venezuela has freed an opposition activist jailed for his role in 2014 anti-government protests as a sign of goodwill amid ongoing talks to mitigate the country's political crisis.

Rosmit Mantilla of the Popular Will party vowed in a Friday statement to fight for the liberation of other political prisoners.

Popular Will cheered his release, but said that another 100 political prisoners remain behind bars. Amnesty International seconded the call for Venezuela to release more activists.

Mantilla was arrested in 2014 on charges that he helped foment violence during a wave of sometimes bloody anti-government protests.

The government has released a handful of activists since it signed on to Vatican-mediated talks last month.
