Calls are getting louder for the Gaza Humanitarian Foundation (GHF) centres to be shut down. They come as another 29 Palestinians were killed at the sites on Wednesday, while seeking food. More than 640 people have been killed since the GHF began operating five weeks ago. The Swiss government has initiated proceedings to dissolve the Geneva branch of the GHF citing legal shortcomings. The UN Secretary-General's office says the globally accepted humanitarian standards must be followed while distributing aid.
