Tunisia's official TAP news agency says a Catholic priest from Poland has been killed and his body had multiple stab wounds and his throat was slit.

The report cites the Tunis archbishopric as saying 34-year-old Marek Marius Rybinski worked at a religious school in the Tunis suburb of Manouba. His body was found Friday in the school parking lot.

In a statement, the Interior Ministry said the killing appeared to be the work of a "group of extremist terrorist fascists," judging by the way it was carried out.

The statement denounced extremists' "exploitation ... of the current exceptional circumstances to make trouble."

A mass uprising toppled Tunisia's autocratic leader a month ago, and the transitional government has struggled to re-establish order.
