Female activists from across the world have set sail for Gaza Strip on board two boats from the Spanish port of Barcelona to take humanitarian aid to the people of the Israeli-besieged territory.

The boats, Amal (hope) and Zaytouna (olive), each having 11 women on board, left Barcelona on Wednesday evening under the banner "The Women's Boat to Gaza," to reach Gaza by early October.

Zohar Chamberlain Regev, a spokeswoman for the group of activists, said that food and medicine are carried on the boats to be distributed among Gazans.

“But mainly we are carrying a message of hope and solidarity, because we think Gazans want that most of all,” she said.

Gaza has been under Israeli siege since June 2007. The siege has caused a sharp decline in standards of living and unprecedented levels of unemployment and poverty. The strip has a population of more than 1.8 million.

Touching upon the Israeli siege on Gaza Strip, Regev said the activists are hoping that Israel would not stop them from entering Gaza.

“We are not heading to an Israeli port so they have no reason to stop us,” she added.

“We think that through this act organized by women, we can give more visibility to the important role of Palestinian women in the fight for freedom,” Regev said.

The Women's Boat to Gaza attempted to deliver humanitarian aid to the coastal enclave in 2015, but the Israeli regime's naval forces boarded its vessel and forced it to change its route.
