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.
Yvette Cooper has called on the government to announce a "clear plan" to tackle refugees and say how many Syrian refugees the country will take in this year.
Labour's shadow home secretary, speaking during an emergency debate in the House of Commons, welcomed the government's recently announced commitment to accept up to 20,000 Syrian refugees over the next five years, but urged it to be more specific about what it will do to ease the refugee crisis.
"We need to know how many [refugees] the government will help this year," she said.
She said: "We need a clear plan ... [a] target for how many people we can take before Christmas, how many over the next 12 months. Britain is showing how much it wants to do, now we need a government that wants to do its bit too."
She also took issue with the government's plan to help refugees only in refugee camps near Syria, arguing that Britain also needed to act in Europe.
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.
