At least three blasts were heard in Baghdad as the Arab League summit began there today, the BBC reported.
The city is blanketed in security; 100,000 members of security forces have been deployed, the international airport is closed to commerical traffic, residents are under curfew, and cell phone networks have been shut off.
As a result, correspondents are having trouble gathering more information about the blasts, but some reporters wrote on Twitter that the blasts sounded like they came from the international zone, formerly the Green Zone, and near the Iranian embassy.
Jalal Talabani, Iraq's president, had just opened the ceremony when the blasts were heard, Agence France Presse reported. Smoke was seen rising from the Salhiyeh neighborhood of Baghdad at around 1:40 p.m. local time.
