"So far, incidents of the interception of food aid being distributed by NGOs can be described as 'sporadic', and we will become more worried if they become persistent," Cephas Zinhumwe, chief executive officer of the National Association of Non-Governmental Organisations (NANGO), told IRIN.
"Individual NGOs such as Care International and NANGO have been, and are still, engaged in initiatives to rectify the issue with the government, to facilitate the uninterrupted activities of relief agencies," he said.
