Three Afghanistan National Army officers were reported missing from an international military training exercise at Camp Edwards on Cape Cod after they disappeared without explanation.

Maj. Jan Mohammad Arash, Capt. Mohammad Nasir Askarzada and Capt. Noorullah Aminyar were all last seen at the Cape Cod Mall on Saturday, the day they were reported missing, said Massachusetts National Guard Col. James Sahady.

“There is no indication that they pose any threat to the public,” Sahady said. In Afghanistan, shootings of American soldiers by rogue Afghan soldiers has been an ongoing problem. Last month, Maj. Gen. Harold Greene was killed by an Afghan soldier in an attack that wounded several other NATO and Afghan soldiers.

The trio missing on Cape Cod were among 200 military professionals from six nations participating in an “senior professional command staff exercise,” Sahady said. They arrived in the Bay State on Sept. 11 for exercises that began Sept. 17 and running through Wednesday.

Such exercises been going on for nearly 10 years, Sahady said, and designed to “promote cooperation and interoperability among the participating forces in the areas of building functional capacities, peacekeeping operations, and enhancing overall readiness.”

The exercise was organized by the Massachusetts National Guard, U.S. Central Command, the Armed Forces of the Republic of Tajikistan, and forces from other partner nations.

A National Guard press release on the event says, “Exercise scenarios will gauge participants’ responses during a global peacekeeping operation while focusing on consequence management capabilities, including appropriate responses to ethnic tension, instability, and protection of human rights.”
