Palestinians in Lebanon include the Palestinian refugees who fled to Lebanon during the Nakba, their descendants, the Palestinian militias which resided in Lebanon in the 1970s and 1980s, and Palestinian nationals who moved to Lebanon from countries experiencing conflict, such as Syria. There are roughly 3,000 registered Palestinians and their descendants who hold no identification cards, including refugees of the 1967 Naksa. Many Palestinians in Lebanon are refugees and their descendants, who have been barred from naturalisation, retaining stateless refugee status. Palestinians in Lebanon, including children of Lebanese mothers and Palestinian fathers, face systemic discrimination, with limited access to employment and social services. While some Palestinian Christians, such as women who gained citizenship through marriage to Lebanese nationals, have been naturalized, the state continues to deny citizenship to others.
