The NGOs may have complained earlier, but today I find that NGOs are worried that some of their staff who were not allowed to come over have been conscripted by the LTTE, and even their families are not being allowed free movement. So I suppose the decision of the government that it was difficult to guarantee their security was right. Even the NGO staff are being held back and conscripted to fight for them.
