WASHINGTON (AFP) - The head of US Central Command urged greater trust and communications with the Pakistani military on Monday amid a diplomatic crisis after US airstrikes killed 24 Pakistani soldiers last month.

General James Mattis made his recommendations after his command, which oversees US military operations across a wide swath of North Africa, the Middle East and Central Asia, released the results of its own investigation into the November 25-26 incident.

A joint US-NATO investigation unveiled last week portrayed a disastrous spate of errors and botched communication in which both sides failed to inform the other about their operational plans or the location of troops. “The strongest take-away from this incident is the fundamental fact that we must improve border coordination and this requires a foundational level of trust on both sides of the border,” Mattis said in a statement. Although the US-Nato probe acknowledged the Americans had relayed “incorrect mapping information” to a Pakistani liaison officer that gave the wrong location for Pakistani troops at border outposts, the CENTCOM report made no mention of discipline of US or NATO personnel. But Mattis directed Nato’s International Security Assistance Force (ISAF) commander General John Allen to take a number of corrective actions to improve the now-moribund relationship with Islamabad, including fostering “improved, mutual trust” between forces working in the mostly lawless border areas.

Troops should also “clarify authorities, responsibilities, and standard operating procedures” in the area as well as conduct formal exercises and drills to improve coordination and reduce chances of conflict.

Mattis also called for “full disclosure of all border area facilities and installations” on both sides of the border, with updates using a shared database and map as well as organizing coordination visits.
