Fifteen Egyptian fishermen who were released by the Tunisian authorities on Friday arrived at Cairo International Airport on Saturday.
The fishermen have been detained at the Tunisian port of Sfax after illegally entering the Tunisian territorial waters.
The Foreign Ministry has warned the fishermen against entering into territorial waters of other countries without permits.
Such acts run counter to the laws of these nations, the ministry said last month.
The warning came in the light of repeated attempts of Egyptian fishermen to fish outside Egyptian territorial waters. Many had been arrested.
