from Michelmore reiterates a verbal conversation between the two, stating that: at the request of the Israel Government, UNRWA would continue its assistance to the Palestine refugees, with the full co-operation of the Israel authorities, in the West Bank and Gaza Strip areas. For its part, the Israel Government will facilitate the task of UNRWA to the best of its ability, subject only to regulations or arrangements which may be necessitated by considerations of military security. In his responding letter, Comay wrote: I agree that your letter and this reply constitute a provisional agreement between UNRWA and the Government of Israel, to remain in force until replaced or cancelled.UNRWA has been criticised by the Israeli government and politicians for alleged involvement with Palestinian militant groups, such as Hamas. Israel has stated that Peter Hansen, UNRWA's former Commissioner-General (1996–2005) "consistently adopted a trenchant anti-Israel line" which resulted in biased and exaggerated reports against Israel. UNRWA has also lodged complaints, for example: Al-Aqsa Intifada 2000 – allegations of Israeli interference with UNRWA operations During the Al-Aqsa Intifada, which started in late 2000, UNRWA often complained that Israeli road closures, curfews and checkpoints in the West Bank and Gaza have interfered with its ability to carry out its humanitarian mandate. The Agency has also complained that large-scale house demolitions in the Gaza Strip have leftover 30,000 people homeless. Israel justifies the demolitions as anti-terror measures. November 2002 allegation that an Israeli sniper killed UNRWA employee In November 2002 Iain Hook, a British employee of UNRWA, was shot and killed by an IDF sniper while working in the Jenin refugee camp, during an operation to locate a Palestinian militant suspected of masterminding a suicide bombing that killed 14 people earlier in 2002. Peter Hansen, head of UNRWA at the time criticized the killing: "Israeli snipers had sights. They would have known who the two internationals (non-Palestinians) were. They did not dress like Palestinians." Death of UNRWA Staff Member in Kalandia Refugee Camp In August 2013, UNRWA released a statement that accused Israel of killing one of its staff members and injuring another in the Kalandia refugee camp during a raid. According to the release from 26 August 2013, "UNRWA deeply regrets to confirm that one of its staff members, a 34-year-old father of four, was shot dead by Israeli forces and killed instantly in an operation in Kalandia refugee camp in the West Bank
