European authorities and aid organizations are warning that criminals may seek to capitalize on the desperation of refugees, with more than 3 million leaving Ukraine since Feb. 24, according to U.N. estimates.
The International Organization for Migration on Wednesday said those concerns were based in reality, pointing to initial reports of traffickers exploiting the large-scale human displacement, including instances of sexual violence. The U.N. agency did not quantify the problem, noting that many cases go unidentified in the immediate aftermath of a displacement event.
