The European Union is condemning Ethiopia's decision to expel two EU diplomats.

EU Development Commissioner Louis Michel told reporters in Brussels Friday that no reason has been given for the expulsion. He called the situation "unacceptable" and said he has asked the Ethiopian ambassador to provide an explanation.

It is not clear if the diplomats have already been deported.

Ethiopian state-run television Thursday reported that police detained two foreign diplomats in the south, near the Kenyan border. The report said the diplomats are accused of trying to smuggle alleged Ethiopian criminals into Kenya.

The European Union is one of Ethiopia's largest aid donors. However, EU officials have been critical of the government's crackdown of opposition leaders and journalists.
