Prominent Venezuelan opposition politician detained hours after release

Prosecutor claims Juan Pablo Guanipa was re-arrested due to non-compliance with terms of release

One of Venezuela's most prominent opposition politicians, Juan Pablo Guanipa, has been detained by security forces just hours after being released from prison, as the South American country's leaders sent mixed signals about their commitment to political reform after Nicolas Maduro's downfall.

Guanipa, who is a close ally of the Nobel laureate Maria Corina Machado, emerged from nearly nine months' detention on Sunday - one of at least 35 political prisoners to be freed over the course of the day.
