CAIRO — Six days after the crash of a Russian charter flight from the Egyptian resort area of Sharm el-Sheikh, the government of Egypt is finding itself increasingly isolated in its resistance to the possibility that a terrorist’s bomb brought down the plane. After standing arm-in-arm with Egypt for six days in discouraging any such discussion of terrorism, even President Vladimir Putin on Friday suspended Russia’s flights to Egypt for fear of another attack, stranding tens of thousands of tourists at the resort. [...] the government of Egypt, critically dependent on the money tourists bring to Sharm el-Sheikh’s resorts, has dismissed every suggestion of a bombing as “premature,” “surprising” and “unwarranted.” Several British news outletsreported Friday that the government based its conclusion about a bombing in part on telephone surveillance of Egyptian militants in the Sinai Peninsula, and reports focused on the chance that an airport employee might have planted an explosive.
