The European Union hopes to provide more than 1 billion euros ($1.1 billion) in aid to Syrian refugees and release another 1 billion euros for Turkey, the host for almost 2 million people who have fled the conflict.

The EU's executive Commission plans to allocate more than 300 million euros to top up its "trust fund" for Syrian refugees.

Johannes Hahn, the commissioner responsible for ties with the EU's neighbors, said Wednesday that "this is a signal and hopefully will stimulate our member states to do the same," and push the total to 1 billion euros.

He also says the Commission is working with Turkey to free up 1 billion euros earmarked for that country's EU membership process as a short-term measure to help deal with the refugee influx.

Austrian police say that about 2,500 migrants and refugees have arrived at the main border point between Austria and Hungary, a day after 5,000 crossed into Austria.

Police spokesman Helmut Marban says the new arrivals were bused to the Hungarian side of the Nickelsdorf crossing point early Wednesday. From there they are walking into Austria.
