A/HRC/10/22 page 28 (e) Unlawful use of incendiary weapons (white phosphorous artillery shells): the use of white phosphorous during a military offensive may be permissible where it is intended to provide cover for troop movements.

Unlawful use of artillery shells (155 mm): there is reliable evidence that artillery shells, which can have a casualty radius of up to 300 metres, were also used in densely populated civilian areas. Unlawful use of flechettes (4 cm darts): Israel is reported to have used 120 mm shells packed with flechettes in populated residential areas; (f) Attacks on medical personnel and ambulances as well as hospitals and denial of medical treatment and access to treatment offered by ICRC and the Palestinian Red Crescent Society; (g) Attacks on schools; (h) Destruction of vital civilian infrastructure; (i) Interference with the provision of humanitarian aid. 103.
