TUNIS (Reuters) - A bomb in a police car exploded on Saturday in the Tunisian capital of Tunis hours before the funeral of assassinated secular opposition political Mohamed Brahmi, a spokesman at the Interior Ministry said.

There were no casualties from the blast near a police station in the residential La Goulette district, Mohammad Ali Aroui said.

The Interior Ministry has accused hardline Islamists of Brahmi's murder.
