The U.N. refugee chief says his agency is working with Jordan to bolster security at a camp for Syrian refugees where reports of drug trafficking, prostitution and other crimes have emerged. According to AP, Antonio Guterres says the Zaatari camp near the Jordanian-Syrian border now is de facto Jordan's fourth-largest city, with a "complex" environment. He told reporters in Amman on Wednesday that security will be "very strongly increased" and special measures will be undertaken to stop criminal activities. Guterres spoke after meeting Prime Minister Abdullah Ensour to discuss mechanisms to ensure that the rule of law is carried out in the camp. He provided no details.
