Iranian President Mahmoud Ahmadinejad confirmed Sunday that his government will attend a major regional conference on Iraq set for this week in Egypt, the Iraqi prime minister's office said.

A statement from Prime Minister Nouri al-Maliki's office said Ahmadinejad telephoned the Iraqi leader and told him Tehran would participate in the meeting Thursday and Friday in the resort of Sharm El-Sheik.

The call was made as top Iranian envoy Ali Larijani flew to Baghdad for talks with Iraqi leaders.

In Tehran, Foreign Ministry spokesman Mohammad Ali Hosseini said Larijani would discuss the conference with Iraqi government officials as Iran has "some questions and ambiguities about the agenda."
