TUNIS (AFP) - A "mentally disturbed" man stabbed and wounded two German tourists on Friday (June 30) in a Tunisian marketplace near the northeastern beach resort of Hammamet, the government said.

The attack on a mother and her 27-year-old daughter took place in the arts and crafts market of the town of Nabeul, the tourism and interior ministries said in a joint statement.

"The incident is not an act of terrorism", the statement said.

The mother was slightly wounded and treated on the spot while her daughter "is in stable condition", the ministries said, adding that the attacker had been detained by police.

Both women were hospitalised but are "out of danger", Imene Hamdi, from the health ministry's press office, told AFP.

Two attacks targeting tourists killed 59 foreigners and a Tunisian police officer in 2015, sending revenues in the key tourism sector plummeting.

The Islamic State in Iraq and Syria (ISIS) militant group claimed the attacks on the National Bardo Museum in Tunis and on a coastal resort near Sousse.
