US troops flew into Monrovia, capital of Liberia, on Thursday to help West African peacekeepers take over security of the city.
According to reports reaching here, the troops, part of the 2,300-strong task force on the ships outside of Liberia, landed Monrovia's Robertsfield airport aboard nine helicopters.
The city of Monrovia appeared quiet after former president Charles Taylor stepped down and handed over power to current President Moses Blah, then vice president, on Monday.
On Tuesday, the rebels agreed to withdraw troops from a two-month siege of Monrovia and promised to pull back completely from the city by noon Thursday, allowing aid and food to flow again to hundreds of thousands of starving people.
The Liberian civil war, which lasted more than 14 years and claimed at least 200,000 lives, flared up again in 1998 following attacks launched by the rebel Liberians United for Reconciliation and Democracy in northern Liberia.
Civil war over the past decade has made Liberia among the most miserable places in the world and the latest unrest since 1998 hasforced some 300,000 Liberians to flee to neighboring countries andleft thousands more dead.
