David Cameron has visited camps in Lebanon and Jordan to meet Syrian refugees who have fled their country's civil war.
The Prime Minister has called on other EU countries to "step up to the plate" and follow Britain's lead by funding refugee camps around Syria.
Mr Cameron said there was a "direct connection" between shortfalls in aid for camps in Lebanon, Jordan and Turkey and the influx of migrants into Europe.
Prime Minister David Cameron has arrived in Beirut to visit refugee camps in Lebanon, which are housing more than a million people fleeing violence in Syria.
He toured the Bekaa Valley settlement, less than a mile from the Syrian border, meeting those affected by the war in the neighbouring country and seeing the conditions they face, as well as seeing how aid sent by Britain is being used.
Lebanon will receive £29 million of the extra £100m pledged by the UK to help with the refugee crisis, which will pay for food packages, clean water, blankets, stoves, mattresses, counselling and play areas for children.
He met a family who are due to be flown to the UK as part of a relocation scheme, following his announcement last week that Britain would take in 20,000 refugees over the next five years.
He was also invited into the tent of a Syrian mother who told him of their fight for survival - revealing she had just five dollars a month to keep and feed her 10 children.
Later, he will visit his Lebanese counterpart Tammam Salam to discuss the refugee crisis.
On a visit to Jordan, David Cameron says that the EU must "follow Britain's lead" and fund more refugee camps around Syria.
The prime minister has insisted the UK will not participate in plans to redistribute 160,000 refugees who have arrived in Europe.
