Hezbollah TV announced Saturday evening that Hezbollah-led opposition forces would withdraw all their gunmen from Beirut in compliance with the Lebanese army's request.
According to an opposition statement, the move comes after the army issued a statement calling on gunmen to get off the street and reopen the roads.
But the statement said a civil disobedience campaign will continue until the group's demands are met.
The announcement came after the Lebanese army overturned government measures against the group, which sparked clashes in and around Beirut that left dozens dead after four days of fighting.
Hezbollah moved Thursday to seize the Sunni neighborhoods of Beirut after its leader Hassan Nasrallah accused the U.S.-backed government of declaring war on his group when it declared the organization's communications network illegal and ordered the removal of the airport security chief for alleged ties to the militants.
On Saturday, Lebanese Prime Minister Fouad Siniora said the decision on the communications issue would be dealt with by the army, which promptly overturned the two anti-Hezbollah measures.
While Siniora in effect backed away from the government decisions to curb the militant group's power, he also toughened his rhetoric against Hezbollah, which he accused of staging a coup.
Death toll reaches 37 in four days of Lebanon clashes
In the latest incident of violence in Lebanon, at least 12 gunmen were killed and 20 wounded in a gunbattle between pro- and anti-government groups in a remote region of northern Lebanon.
Saturday's gunbattle occurred in the town of Halba in Akkar, a remote Sunni region in northernmost Lebanon when fighters loyal to Sunni leader Sa'ad Hariri and the government clashed with members of the Syrian Social Nationalist Party, a secular pro-Syrian group allied with the Shiite Hezbollah.
The pro-government fighters stormed the office of the SSNP and set it ablaze after the gunbattle.
The number raises to 37 the death toll since Shi'ite-Sunni sectarian erupted in Beirut on Wednesday and spread to other regions.
Earlier Saturday, a Shi'ite shopowner opened fire on a funeral procession Saturday in a Sunni neighborhood of Beirut, killing two and wounding six, a day after Shi'ite gunmen swept through the Lebanese capital's Muslim sector, police and witnesses said.
The shooting in the neighborhood of Tarik Jadideh underlined the state of lawlessness and the sharpened sectarian tensions that have engulfed the Lebanese capital's Muslim sector since Sunni-Shi'ite fighting erupted on Wednesday resulting in Hezbollah's takeover of neighborhoods from Sunnis loyal to the U.S.-backed government.
By Saturday afternoon, the army had replaced Hezbollah in most of the Muslim neighborhoods seized by the militant group.
Tarik Jadideh was a stronghold of Sunni supporters of majority coalition leader Sa'ad Hariri. Shi'ite gunmen did not enter that neighborhood, where Lebanese troops deployed to prevent an onslaught by Hezbollah.
Elsewhere in the capital Saturday, Beirutis cautiously ventured out in small numbers to streets held by both Lebanese troops and lingering bands of Shi'ite gunmen.
Also on Saturday, at least 212 Jordanians, mostly students, were evacuated from Lebanon in coordination between the Foreign Ministry and the Jordanian embassy in Beirut, according to an official statement.
The Jordanian citizens, who arrived aboard four buses, decided to leave Lebanon "in the light of the deterioration of the security situation there," the Foreign Ministry said.
Beirut had a quiet night Friday after the worst sectarian violence since the end of the 1975-90 civil war, in which 150,000 were killed and parts of the city wrecked as it was carved into warring sectarian enclaves. But the violence moved outside the capital, leaving 20 more people dead in addition to the 17 killed in Beirut.
People ventured out to check on their shops, cars and to stock up on food after days of being trapped inside by the fighting.
The Christian sector of Beirut was peaceful and was not involved in the violence.
The army, which had stayed on the sidelines until moving into Beirut neighborhoods on Saturday, brought in more armor and troops to seal off neighborhoods where top pro-government leaders - Hariri of the Sunnis and Walid Jumblatt of the Druze - were holed up in their residences.
Violence also erupted in the mountain town of Aley east of Beirut. Eight people were killed there on Friday night. Another civilian died in the clashes in the southern city of Sidon.
Hezbollah's power was demonstrated dramatically Friday morning when it forced off the air the TV station affiliated with Hariri's party. Gunmen also set the offices of the party's newspaper, Al-Mustaqbal, on fire in the coastal neighborhood of Ramlet el-Bayda. Shi'ite gunmen from Hezbollah and Amal, and allied group, roamed unopposed through the deserted streets of neighborhoods once dominated by supporters of Hariri and the government.
Lebanon's army only intervened after the building was set ablaze. Troops provided cover for firefighters, who eventually extinguished the flames.
The army also evacuated employees from the TV station, but only after gunmen massed near it and threatened to destroy it, said Nadim Mounla, the station's chief.
With Hariri and Jumblatt besieged in their residences in Muslim western Beirut, officials of the pro-government majority called an emergency meeting of legislators in a mountain town in the Christian heartland northeast of Beirut, said LBC TV, a pro-government Christian station.
Lebanese political commentators have branded the violence an attempted military coup.
The army has largely avoided getting involved in the street battles, preferring to remain above the political fray for fear of being dragged into the conflict. The institution could break up on sectarian lines if it takes on Hezbollah's powerful militia or any major party.
Dozens of fighters from the Syrian Social Nationalist Party, a Hezbollah ally, also appeared in the streets off Hamra, some masked and carrying rocket-propelled grenade launchers.
Shops in the normally bustling commercial district closed save for a few pharmacies and grocery stores.
The unrest virtually shut down Lebanon's international airport for a third day and barricades closed major highways. Hezbollah first blocked roads in Beirut on Wednesday to enforce a strike called by labor unions, but confrontations quickly spread across the city.
Later, Hariri made a televised appeal to Nasrallah seeking to calm the conflict.
"My appeal to you and to myself as well, the appeal of all Lebanon, is to stop the slide toward civil war, to stop the language of arms and lawlessness," said Hariri, son of former Prime Minister Rafik Hariri, who was assassinated in 2005.
The clashes are the latest turn in a test of wills between the Hezbollah-led opposition and the government of Siniora. The U.S.-backed government has only a slim majority in parliament, and the two sides have been locked in a 17-month power struggle that has kept government at a standstill.
The fight could have implications for the entire Middle East at a time when Sunni-Shi'ite tensions are high. The tensions are fueled in part by the rivalry between predominantly Shiite Iran, which sponsors Hezbollah, and Sunni Arab countries like Saudi Arabia and Egypt.
