A21-year-old Tunisian student at Pisa University drowned in a lake near L'Aquila in Abruzzo Tuesday, after a 21-year-old Pakistani man drowned there since June.

The student dived into Sinizzo Lake at San Demetrio ne' Vestini shortly after eating lunch and did not resurface, probably after suffering congestion, local police said.

The Pakistani victim was named as Rahmat Hussain.
