TEHRAN, Iran -- The Latest on suicide bombing targeting elite Revolutionary Guard (all times local):
Iran's Foreign Minister Mohammad Javad Zarif is linking a suicide bombing targeting the country's elite Revolution Guard to an ongoing, U.S.-sponsored Mideast meeting in Warsaw.
Zarif added that the "US seems to always make the same wrong choices, but expect different results."
Iranian state media have blamed the al-Qaida-linked Sunni extremist group Jaish al-Adl for a bus bombing that killed at least 20 members of Iran's elite paramilitary Revolutionary Guard and wounded 20 more.
Other semi-official news agencies also reported Jaish al-Adl, or "Army of Justice," had claimed the attack.
The attack Wednesday struck Iran's southeastern Sistan and Baluchistan province, where the group has launched other attacks.
The bombing comes on the day of a U.S.-led conference in Warsaw that included discussions on what America describes as Iran's malign influence across the wider Mideast.
A state-run news agency in Iran is reporting a suicide bombing in the country's southeast has killed at least 20 elite Revolutionary Guard personnel and wounded 20.

The province, which lies on a major opium trafficking route, has seen occasional clashes between Iranian forces and Baluch separatists, as well as drug traffickers.
