Algeria's Safia Djelal of Algeria broke the javelin F55/56/57 world record on the opening day of the International Paralympic Committee (IPC) Athletics Grand Prix in Tunis.
Djelal, winner of a Paralympic silver medal at London 2012, threw 25.71 metres to take a gold ahead of Kenya's Cecilia Wangechi Mwangi, second with 18.86m.
On an action-packed first day, multiple Paralympic and world champion Walid Ktila was at the double as he won both the 100 metres and 800m in the T33/34 classifciation to the delight of the home crowd.
Ktila proved too strong for the rest of the field in the 100m, powering home in a time of 16.15sec to cross the line 3.78 seconds in front of nearest challenger, Kuwait's Ahmad Almutairi
The 29-year-old, who secured a clean sweep of all the events at the recent Grand Prix in Dubai, then took the 800m honours, posting 1min 59.05sec to finish ahead of Great Britain's Daniel Bramall, who finished second in 2:38.34.
The success for the host nation did not stop there however as Yassine Gharbi continued his recent run of excellent form by winning the 400m T51/52/53/54 event, beating Algeria's Maamar Harachif by over a second.
Gharbi then led a Tunisian one-two in the 800m as his time of 1:44.25 saw him edge compatriot Fethi Zouinkhi, while the hosts' dominance was maintained by Abbes Saidi, who cruised to victory in the men's 800m T36/37/38 thanks to clocking 2:06.53.
Tunisia's Somaya Bousaid won gold in the 400m T13/37/38, powering round the track in 58.96, which was enough to beat team-mates Sonia Mansou and Neda Bahi.
The hosts didn't quite manage a clean sweep of all the events as there was further success for Algeria's double world champion Lahouari Bahlaz, whose final throw of 9.35m in the F32 shot put gave him victory ahead of compatriot Karim Betina.
Raoua Tlili of Tunisia demonstrated why she is currently the best in the world as she clinched shot put F40/41 gold, while home favourite Hania Aidi was the victor in the women's javelin F53/54.
The men's discus F51/53/54 also went to the form books as Tunisian world number one Mohamed Zemzemi claimed the win ahead of Algeria's Mohamed Berrahal, and Zemzemi's team-mate Maroua Ibrahmi repeated the feat in the women's shot put F32/33/34.
