The Israeli Occupation Authorities (IOA) released Tuesday evening the Palestinian lawyer and activist Shireen Issawi 39 after spending 43 months behind Israeli bars.
Shireen was freed after Israeli Supreme court reduced her 48-month sentence to 45 months.
Her brother Medhat sentenced to eight years is also scheduled to be brought before court in the coming days.
The two were accused of passing information and transferring funds between prisoners and political organizations banned by Israeli occupation authorities.
The Issawis are themselves not strangers to imprisonment. Shireen and Medhat were held more than once in Israeli jails.
