The pledge to cleanse Sinai was made by Mr Suleiman to Yuval Diskin of the Israeli Security Agency (ISA) after he complained about the smuggling of weapons across the border with Gaza. According to a cable sent in November, 2007, Mr Diskin met Rob Danin, the US deputy assistant secretary of state, and Mark Kimmitt, the deputy assistant defence secretary, in Tel Aviv and told them that the Sinai peninsula had now become a “weapons and explosives warehouse” for operations in Gaza, Egypt and Israel.
