BAGHDAD (AP) -- Officials say the United States and Iran have set a date for ambassador-level talks in Baghdad on the deteriorating security situation in Iraq.
Tuesday's face-to-face will be the first such meeting since late May.
The talks come amid US allegations that Tehran is supporting violent Shiite militias in Iraq.
Iraq's fragile government has been pressing for another meeting between the two nations with the greatest influence over its future. Iran has repeatedly signaled its willingness to sit down.
The last meeting, in May, marked a break in a 27-year diplomatic freeze between the US and Iran. But following that meeting, the U-S accused Iran of failing to scale back a concerted effort to arm militants and harm US troops.
Tensions also have risen over Tehran's detention of four Iranian-American scholars.
