Al-Jazeera Video: Egypt security forces storm NGO offices

"Egyptian security forces have stormed the offices of 17 human rights and pro-democracy groups.The ruling military said it is investigating how the groups are funded.

At least two US rights groups - the National Democratic Institute (NDI) and the International Republican Institute (IRI) - were targeted in the operation.

The US expressed deep concern over the raids and urged Egyptian authorities to immediately halt "harassment" of non-governmental organisation staff.

The US state department said the raids were "inconsistent with the bilateral cooperation we have had over many years", hinting it could review its military aid if they continued.
