The United Nations is now aiding nearly 400,000 Syrians across Lebanon, according to a new report issued Friday, as the refugee crisis quickly outpaces projections and local communities are strained.

The weekly rate of new refugee arrivals is increasing, according to the report. Aid groups projected there would be over 500,000 refugees in the country by the summer but the current influx of people is quickly outpacing that estimate.

The U.N. High Commissioner for Refugees (UNHCR) is struggling to aid the huge refugee population that is taxing the local communities hosting Syrians with funding far below their requirements.
