Tunisian policeman dies after knife attack

A Tunisian police officer who was stabbed by a suspected Islamist in Tunis has died.

The suspect, named as Zied Gharbi, was arrested on Wednesday after two policemen were wounded with a knife near the parliament.

The attack was close to the Bardo museum where 21 people, mostly European tourists, were killed in an attack by gunmen in March 2015.

Tunisia suffered two other major attacks that year, one against tourists at the beach resort of Sousse and the other against presidential guards in the capital.

"Our colleague Riadh Barrouta died Thursday after the terrorist attack in Bardo yesterday," Walid Hkima, a national security spokesman, said.

The 2015 attacks severely damaged the economy of the North African country, which has a large tourism sector at its Mediterranean beaches.

Since then, security has been boosted at strategic sites while authorities have cracked down on militants, dismantling dozens of cells.
