Hamas and Islamic Jihad called on Thursday for the Palestinian people and different factions to reach a comprehensive national strategy to confront Israel. 

They described the unified plan as a "duty" and called on a meeting of secretaries-general of the Palestinian factions.

This comes after President Mahmoud Abbas held faction meetings to discuss Israel's large-scale assault on Jenin, with the two Islamist groups sitting out. 

"The occupation's plans to end the Palestinian presence in the occupied 48 lands, as well as the size of the risks, challenges and violations that our people are exposed to, oblige us to take action to confront this, in a way that responds to the aspirations of our people for liberation and return," the statement read.

"This achievement of the Palestinian resistance would not have been achieved without the unity of our people and its fighters in the field, which requires all of us to build and accumulate on this great achievement," it continued.
