The number of migrants at the EU’s borders reached a record high of 107,500 in July, officials say, as a sharp surge in expected asylum requests was reported in Germany.
Germany has seen a wave of migration from Syria and the Balkans, and now says it could receive as many as 750,000 asylum seekers this year.
The EU has been struggling to cope with migrant arrivals in recent months.
France and the UK say they will sign a deal to tackle the crisis in Calais.
Over the summer, thousands of migrants have sought to get to the UK through the Channel Tunnel from makeshift camps around the northern French city.
France’s Interior Minister Bernard Cazeneuve and his British counterpart Theresa May say they will sign a deal there on Thursday to strengthen their countries’ co-operation on security, the fight against criminal smugglers, human traffickers, and clandestine immigration.
In early August, the UK pledged to add €10m (£7m) to a fund established in September 2014 to secure the port of Calais, and initially endowed with €15m over three years.
