Tunisia on Wednesday announced the arrest of a suspect in the murder of an aerospace engineer described by Palestinian Islamist movement Hamas as one of its members.

Mohamed Zaouari, 49, was killed in a hail of bullets at the wheel of his car outside his house in Tunisia's second city Sfax in December 2016. "The two people who carried out the assassination were identified -- both were of Bosnian nationality," prosecution spokesman Sofiene Sliti said.

One of the suspects was arrested on March 13 in Croatia, he said, without giving details on the other individual. The government earlier confirmed that "foreign elements" had been involved in the killing of the Tunisian-Belgian citizen, which sparked outrage in Tunisia.
