An injured member of the Palestinian Fateh Movement stands guard during clashes that erupted between the Palestinian Fatah Movement and Islamists in the Palestinian refugee camp of Ein el-Hilweh near the southern port city of Sidon, Lebanon, Sunday, April 9, 2017.
An adjacent highway has been cut and patients moved from the Sidon governmental hospital next to the camp. Sidon's government hospital was struck by a rocket.
The violence began on Friday when the joint Palestinian security force sought to deploy throughout the camp and met resistance from the Sunni Islamist Badr group.
The fighting has prompted security measures outside the camp, which Lebanese security forces do not enter by long-standing agreement.
Under a tacit deal stuck after the 1975-1990 civil war, the Lebanese army does not enter the country's 12 official Palestinian refugee camps, where the factions themselves handle security.
The decision to send the joint force into the camp was taken during a meeting in Sidon for the Palestinian political leadership and the camp's Islamic factions.

He said the airline was conducting a review and reaching out to the passenger to "further address and resolve this situation". Before yesterday's incident escalated, United reportedly asked for volunteers to give up their seats on the flight.
Fatah's head in Lebanon said the security force would deploy in all areas of the camp with the aim of disbanding the Badr group and arresting its leader, Bilal Badr.
Information received by Asharq Al-Awat from inside the camp said that Bilal Badr is now in the protection of the terrorist Fatah al-Islam leader Osama al-Shehabi.
The situation was calmer on Tuesday though gunfire could still be heard in the camp, witnesses said.
The spokesman for the Council of Palestinian Scholars in Lebanon said the radical groups were issuing fatwas authorizing the killing of people they disagreed with. "These groups do not abide by any oaths or promises".
Clashes have erupted intermittently in recent months in Ain al-Hilweh. The camp was established in 1948 to host Palestinians displaced by Israeli forces during the establishment of Israel.
