In pictures: Lebanon's Syria refugees

Lebanon has placed new restrictions on Syrians entering the country to slow the flow of asylum seekers trying to escape the Syrian civil war.

Syrians entering Lebanon face new restrictions, and will require a visa to enter the country. Previously, travel between the two countries was largely unrestricted.

Millions have fled Syria's civil war, which killed more than 76,000 people in 2014.

Officially, there are 1.1 million Syrians living in Lebanon. However, the real number is believed to be much higher: about 500,000 in the country are thought to be unregistered.

The influx is placing massive strains on Lebanon's infrastructure. One in five people living in the country is a Syrian refugee.

Many Syrian refugees face hostility from the Lebanese population who fear their presence will raise sectarian or religious tensions, or even spark another civil war.

The Syrian uprising began with protests against President Bashar al-Assad's rule in 2011 and degenerated into civil war a year later.
