The Latest: UN rights body registers Puigdemont's complaint

The Latest on Catalonia's political struggle with Spain (all times local):

1 p.m.

A United Nations spokeswoman says the UN Human Rights Committee has registered a complaint by Catalonia's former president who alleges that Spain has violated his political rights.

Carles Puigdemont is in preliminary custody in northern Germany awaiting a court's decision on whether to proceed with an extradition request by Spain.

Julia Gronnevet, a media officer with the Geneva-based UN body, says the complaint was registered Monday. She added no further information can be shared because the case is "confidential."

A group of lawyers and human rights experts launched legal action in March claiming that Spain has violated human, civil and political rights in its crackdown on Catalonia's independence bid.

The registration means that the Spanish government has now six months to respond with any information or observations to the human rights body.

Catalonia's transit authorities say demonstrators have blocked motorways and roads in the northeastern Spanish region, amid sustained protests over the detention of the former Catalan leader Carles Puigdemont.

The separatist politician is in preliminary custody awaiting a northern German court's decision on an extradition request by Spain.

The regional transportation service in Catalonia says a main motorway through eastern Spain is blocked by protesters in Figueres, near the border with France, as is a national road between Tarragona and Valencia.

Protesters also caused disruptions in the early hours of Tuesday in several roads in central Barcelona, the regional capital.

Further decisions in Germany appear unlikely before Easter. A court in Schleswig will decide on formal pre-extradition custody and whether his extradition is admissible.

Such cases are typically dealt with in writing, without a hearing, though one is possible.
