Israel says it is to stop using artillery shells containing white phosphorus, which it was criticised for during the 2008-09 Gaza conflict.
The shells will be replaced with types based completely on gas, the military said in a statement.
Rights groups condemned Israel’s use of white phosphorus during the Gaza conflict because of its severely harmful effects on civilians.
International law restricts the use of white phosphorus on the battlefield.
The Israeli military said the existing shells contained “minimal amounts” of white phosphorus, and would be “removed from active duty soon”.
Three years ago, Israel promised to draw up new rules on the use of shells containing white phosphorus, in the wake of the Gaza war.
During the three-week offensive, Israel used white phosphorus rounds in densely populated areas, the UN and Human Rights Watch said.
Part of a UN compound burned down after it was hit by chunks of the burning chemical which ignites on contact with air.
Human Rights Watch said Israel “deliberately or recklessly” used white phosphorus shells in violation of the laws of war, causing “needless civilian deaths”.
Israel has insisted that its use of white phosphorus in the conflict was permitted under international law and that it sought to avoid unnecessary civilian deaths in Gaza.
As a weapon, white phosphorus is used to mark enemy targets and to produce smoke for concealing troop movements. It can also be used as an incendiary device against enemy positions.
Its effects however can be extremely harmful. If burning white phosphorus lands on a person’s skin, it can go through to the bone. Toxic phosphoric acid can also be released into wounds, risking phosphorus poisoning.
A protocol to the 1980 Convention on Conventional Weapons bans the use of white phosphorus as an incendiary weapon against civilian populations or in air attacks against enemy forces in civilian areas.
