BEIRUT (AP) — The Lebanese and Palestinian presidents agreed Wednesday that Palestinian factions won't use Lebanon as a launchpad for any attacks against Israel, and to remove weapons that aren't under the authority of the Lebanese state.

The announcement was made during a meeting between President Joseph Aoun and Palestinian President Mahmoud Abbas, who arrived earlier in the day beginning a three-day visit to Lebanon, his first in seven years.

Lebanon's government is seeking to establish authority throughout the country, mainly in the south near the border with Israel after the 14-month Israel-Hezbollah war that ended in late November with a U.S.-brokered ceasefire.

The 12 Palestinian refugee camps in Lebanon aren't under the control of the Lebanese state, and Palestinian factions in the camps have different types of weapons. Rival groups have clashed inside the camps in recent years, inflicting casualties and affecting nearby areas.

It wasn't immediately clear how the weapons would be removed from the camps, which are home to tens of thousands of Palestinians, many of them descendants of families that fled to Lebanon after Israel was created in 1948.

Abbas' Fatah movement and the militant Hamas group are the main factions in the camps. Smaller groups, including some jihadi factions, also have a presence in the camps — mainly in Ein el-Hilweh, which is Lebanon's largest Palestinian refugee camp and located near the southern port city of Sidon.

A joint statement read by the Lebanese presidency's spokeswoman, Najat Sharafeddine, said that both sides have agreed that weapons should only be with the Lebanese state, and the existence of “weapons outside the control of the Lebanese state has ended.”

The statement said that both sides have agreed that Palestinian camps in Lebanon aren't “safe havens for extremist groups.” It added that “the Palestinian side confirms its commitment of not using Lebanese territories to launch any military operations.”

In late March, Israel intensified its airstrikes on Lebanon in response to Hamas allegedly firing rockets at northern Israel from southern Lebanon.

Shortly after the wave of airstrikes, the Lebanese government for the first time called out the Palestinian group and arrested nearly 10 suspects involved in the operation. Hamas was pressured by the military to turn in three of their militants from different refugee camps.

The nearly 400,000 Palestinians in Lebanon are prohibited from working in many professional jobs, have few legal protections and can't own property.
