More than 300 Syrian refugees headed back home to Syria in a convoy on Tuesday, leaving two remote northeastern towns in crisis-stricken Lebanon where anti-refugee sentiment has been surging in recent months.

Lebanese officials have long urged the international community to either resettle the refugees in other countries or help them return to Syria. Over the past months, leading Lebanese political parties have become increasingly vocal, demanding that Syrian refugees go back.

A country of about 6 million people, Lebanon hosts nearly 780,000 registered Syrian refugees and hundreds of thousands who are unregistered — the world’s highest refugee population per capita.

In the northeastern town of Arsal, Syrian refugees piled their belongings onto the back of trucks and cars on Tuesday as Lebanese security officers collected their U.N. refugee agency cards and other paperwork before clearing them to leave.
