The European Union foreign policy chief says the bloc is launching an appeal against last month's EU court ruling that ordered the Palestinian group Hamas removed from its terror list for technical reasons.

Federica Mogherini said Monday the council of ministers will challenge some of the court's finding and consider future action to avoid similar annulments.

Hamas was put on the EU terrorist list as part of broader measures to fight terrorism in the wake of the Sept. 11 attacks and its funds were frozen. Hamas has long contested the classification.

An EU high court on Dec. 17 said the reason for listing it was based too much on media and Internet reports, and not enough on acts examined by competent authorities.
