Lebanese Prime Minister Rashid Karami urged militia leaders today to pull their men from the lawless streets of Beirut and called for the return of Syrian troops to maintain order in the chaotic Lebanese capital.

Karami, a Sunni Moslem, made the statement after an emergency meeting with House Speaker Hussein Husseini and Defense Minister Adel Osseirane, both Shiite Moslems, and Education Minister Selim Hoss, a former prime minister.

The four leaders made their plea for the deployment of Syrian soldiers following a week of inter-Moslem street fighting, a resumption of Shiite-Palestinian battles around the Burj al Barajinah refugee camp and renewed hostilities at the line separating Moslem west Beirut and Christian east Beirut.

Hoss left for Damascus tonight to press Syrian leaders to consider the request for troops. Karami said he doubted that any other force could guarantee the safety of the war-plagued citizenry or the implementation of security agreements.

Karami called on two other Cabinet members who head militias -- Tourism Minister Walid Jumblatt, leader of the Druze forces, and Justice Minister Nabih Berri, leader of the Shiite Amal forces -- to abide by the Damascus accord.

The request to Syria is another sign of Lebanon's increasing dependence on Damascus. Despite similar pleas in recent months, however, Syria has been reluctant to be drawn into the Beirut area's civil warfare, preferring to send observers to help supervise security measures. Karami's request was made in the absence of President Amin Gemayel, who is visiting West Germany.

Meanwhile, shelling resumed at the line separating Christian and Moslem areas. The Lebanese Army said two soldiers were killed and several were wounded.
