The US President Barack Obama and German Chancellor Angela Merkel discussed the ongoing refugee crisis in Europe during a phone call on Thursday.
The White House announced both leaders agreed that an upcoming donors' conference in London would create an opportunity to help start global efforts on the crisis, the White House said in a statement.
Obama told Merkel he is considering organising a summit for world leaders at the UN General Assembly in September to make commitments to address the refugee crisis.
"The two leaders committed to working together over the coming months to help protect and provide for the millions of people whose lives have been upturned by war," the statement added.
The German government said over 1 million refugees, more than 400,000 of which are coming from Syria, arrived in Germany last year, while almost 4,000 refugees died trying to cross the Mediterranean.
