The UK is to provide resettlement to “thousands” more Syrian refugees in response to the worsening humanitarian crisis, David Cameron has announced.

No figure has been decided but the prime minister said the extra refugees would come from camps bordering Syria, not from among those already in Europe.

Britain, he said, would act with “head and heart” to help those most in need.

He also announced a further £100m in humanitarian aid for those in camps in Syria, Turkey, Jordan and the Lebanon.

Earlier this week, Mr Cameron said accepting more people was not the simple answer to the situation, described by some as the worst humanitarian crisis since World War Two.
