Israel accuses Mohamed el-Halabi, a manager of the aid group's Gaza office, of diverting millions of dollars from World Vision's budget to the Islamic militant group Hamas.

The international charity World Vision said on Monday that Israel has accused the charity's Gaza Strip director of funnelling what appears to be an impossible sum of money to Hamas.

Mohamed el-Halabi established a "systematic and sophisticated mechanism" to divert up to $50 million over the years to the group, which rules Gaza, creating fictitious humanitarian projects and doctoring inflated receipts in order to get the funds to Hamas.
