BAGHDAD, April 29 (Reuters) - Iraq's foreign minister said on Sunday he was confident Iran would attend a meeting of major powers in Egypt this week that will seek ways to stabilise Iraq. Hoshiyar Zebari told Reuters that Iran's response would be given by senior Iranian official Ali Larijani, who he said would visit Baghdad later on Sunday. Zebari said there was a "high possibility" that Iran and the United States would hold a bilateral meeting at the May 3-4 meeting in the Egyptian resort of Sharm el-Sheikh, although not necessarily at the ministerial level.
