Asha for Education, of Maoists?
This is an old issue but still worth noting. The infamous charity organization - Asha for Education - has been funding Maoists, says CNN-IBN. AID, a similar politically motivated organization can also be involved as they both work very closely in U.S.
CNN-IBN's SIT met with a Western Union money transfer agent, Shahbuddin who admitted that a lot of NGOs were in collusion with Maoists."Almost all the NGOs are corrupt and have got links with Maoists. The funds are, indeed, being siphoned off to Naxals," he told the SIT. Donations run into crores, often made in cash. Audits are rare, so naturally the state government is concerned.
Samanvaya Ashram in Bihar is a specific NGO in question. I cannot find the article where CNN-IBN reported this, but Asha/AID have been funding this NGO for a while.
