U.S. Secretary of State Mike Pompeo has held a video conference call with the Taliban during which the top U.S. diplomat warned the insurgents against attacking American troops in Afghanistan, the Department of State says.

A statement said Pompeo and the Taliban's Qatar-based chief negotiator, Mullah Abdul Ghani Baradar, on June 29 discussed implementation of a February agreement between Washington and the militants.


"The Secretary made clear the expectation for the Taliban to live up to their commitments, which include not attacking Americans," department spokeswoman Morgan Ortagus said.

Earlier, the Taliban said Baradar reaffirmed during the call the group's commitment to the peace process in Afghanistan and reiterated a pledge not to strike U.S. forces.

The call comes as U.S. President Donald Trump faces mounting pressure to explain his actions after being reportedly told that Russian spies last year had offered and paid cash to Taliban-linked militants for killing American soldiers.

The White House has said Trump wasn't briefed on the intelligence assessments because they haven't been fully verified and were not deemed credible actionable intelligence.

U.S. - Taliban deal

Meanwhile, the U.S.-Taliban deal is at a critical stage at a time violence in Afghanistan has continued since a three-day cease-fire at the end of May. The Afghan National Security Council said June 30 that, since February, the Taliban had on average staged 44 attacks per day on Afghan security forces.

Under the accord, the United States agreed to reduce its forces in Afghanistan from 12,000 troops to 8,600 by mid-July. If the rest of the deal goes through, all U.S. and other foreign troops will exit Afghanistan by mid-2021.

The New York Times reported last week that U.S. intelligence officials concluded months ago that Russian military intelligence offered bounties to Taliban-linked militants to kill U.S. troops.

Subsequent reports by The New York Times and Washington Post reported several American soldiers may have died last year as a result of the bounties.

In particular, U.S. officials are investigating an April 2019 attack on an American convoy near Bagram Airfield, the largest U.S. military installation in Afghanistan.

At the time of the attack, the Defense Department identified those killed as Marine Staff Sergeant Christopher Slutman, Sergeant Benjamin Hines, and Corporal Robert Hendriks.

The Taliban and the Department of State did not specifically say whether Pompeo and Baradar spoke about the report.

Taliban spokesman Suhail Shaheen said in a series of tweets that the two sides discussed "foreign troop withdrawal, prisoner release, start of intra-Afghan dialogue, and reduction in [military] operations."

"We are committed to starting inter-Afghan talks, as we have said before, but delays in the release of prisoners have delayed inter-Afghan talks," Shaheen tweeted, referring to a pledge by Afghan authorities to release 5,000 Taliban prisoners as a condition to start the negotiations.

Baradar "noted that according to the agreement, we will not allow anyone to use Afghan soil against the security of the United States and other countries," he also wrote.
