The protest has been organised by the Scottish Palestinian Solidarity Campaign and the ATUC amongst others.
Brian Carroll of the ATUC said, "We are calling on all citizens and trade unionists to come along and support Gaza in a week which has seen a UN school targeted amongst many other atrocities.
"It has never been more important to join in the global mass protest.
"With a ground assault now adding to the relentless air and sea attacks, the death toll now stands at well over 1,000, with more than a quarter of these children. Thousands more have been injured. Homes, hospitals, schools - all targets. Almost 120000 have been forced from their homes.
"THIS HAS TO END!! Let's stand with Gaza!"
