Rebel fighters carry their weapons as civilians and the rebel fighters who left the Homs district of Waer under a local truce, arrive in buses at Idlib city.

Buses carrying Syrian rebel fighters and their families safely reached the northwestern city of Idlib on Thursday after withdrawing from Homs under a local ceasefire agreement, the Syrian Observatory for Human Rights said.

The United Nations presided over the implementation of the deal, which the mayor of Homs said involved 300 fighters and 400 members of their families leaving Waer, the last rebel-held area of the city that was a center of the uprising against Syrian President Bashar al-Assad earlier in the conflict.

The Observatory said about 750 people had left, including fighters from the al-Qaeda-affiliated Nusra Front and fighters linked with ISIS.

ISIS does not have a major presence in western Syria.

Four buses arrived in Idlib overnight out of a total of around 15 that left Homs, and the rest arrived during the day on Thursday, Observatory director Rami Abdulrahman said. The Britain-based Observatory tracks the conflict through a network of contacts on the ground.

Lebanon-based al Mayadeen TV, which has good contacts in Syria, reported the “operation was completed” on Thursday.

Some diplomats say local ceasefires may be the most effective way of gradually bringing peace to Syria, where more than 250,000 people have been killed during nearly five years of conflict. However, one such ceasefire concluded in Homs in 2014 was widely seen as a forced surrender.

In late September, Iran and Turkey, which back opposing sides in the Syrian conflict, helped to broker local ceasefires in two villages near Idlib and a town on the Lebanese border.

A diplomat who tracks Syria said there could be more local ceasefires. The United States has said they could happen more frequently, after world powers called for a nationwide truce to halt Syria’s civil war.
