Tunis - Tunisian security forces engaged in a gunbattle overnight on Saturday as they arrested a suspect in last July's murder of opposition politician Mohamed Brahmi, the interior ministry's spokesperson said.
Brahimi was the second of two opposition politicians to have been assassinated last year by suspected jihadists as Islamist violence rocked the North African country, which was the birthplace of the Arab Spring revolutions in 2011.
The security forces "surrounded a house (near the capital Tunis) where a terrorist group had holed up. Following a sustained exchange of fire, four elements were arrested," interior ministry spokesperson Mohamed Ali Aroui told AFP.
"Among them is Hmed el-Melki, alias 'Somali,' one of the elements implicated in the assassination of the martyr Mohamed Brahmi," he said.
"The interior ministry stresses that it was a successful operation," the spokesperson said without revealing the identities of the other suspects.
