A/HRC/12/48 page 138 576. Secondly, the claim that this result was neither intended nor anticipated has to be reviewed carefully. In the first place the Mission affirms the result to be reviewed is not fragments and wedges landing in the compound but ten shells landing and exploding inside the compound. It is difficult to accept that the consequences were not appreciated and foreseen by the Israeli armed forces. 577. Those in the Israeli army who deploy white phosphorous, or indeed any artillery shells, are expertly trained to factor in the relevant complexities of targeting, including wind force and the earth’s curvature. They have to know the area they are firing at, possible obstacles in hitting the target and the other environmental factors necessary to ensure an effective strike. It is also clear that, having determined that it was necessary to establish a safety distance, the presence of the UNWRA installations was a factor present in the minds of those carrying out the shelling. 578. The question then becomes how specialists expertly trained in the complex issue of artillery deployment and aware of the presence of an extremely sensitive site can strike that site ten times while apparently trying to avoid it. 579. The Mission’s scepticism that the result was not anticipated is confirmed by the fact that from around 8 a.m. on 15 January UNRWA officials began a series of calls to a number of officials explaining precisely what was going on. These calls were made to the appropriate people at COGAT/CLA as a result of prearranged coordination and further reinforced by the numerous calls by the Deputy Director of UNRWA to senior Israeli military officials in Tel Aviv. 580. In particular, the Israeli military officials were informed that shells had indeed struck inside the compound by the series of phone calls made by UNRWA officials. 581. The Mission is in possession of information that indicates a senior UNRWA official called the head of HCC in Tel Aviv and a number of his immediate subordinates several times. In particular a call was made at 10.31 a.m. by the official to the Israeli armed forces to explain that white phosphorous had landed in the compound and had set fire to the warehouse. He was told “by Tel Aviv” that the firing had stopped. To be clear, this means that by 10.30 a.m. at the latest channels of communication had been opened between Tel Aviv and those on the ground in Gaza City responsible for the firing of the shells, albeit not necessarily directly, but sufficient to be receiving reports of what was going on from Israeli troops on the ground. 582. At 10.30 a.m. staff at the UNRWA compound noted five white phosphorous container shells had discharged in the confines of the compound. At 10.40 a.m. the UNRWA official was again in direct communication with Tel Aviv explaining specifically that “the targeting is taking place in the vicinity of the workshop” and requiring that the Israeli armed forces desist immediately. In particular, he pointed out that what was required was a cessation of the firing for a sustained period of time to allow staff to bring the fire under control. 583. At 11.17 a.m. the same senior UNRWA official was informed in a phone call from UNRWA staff in the compound that a further two rounds had impacted “within the last ten minutes”.
