Oil falls below $100 as U.S.-Iran tensions persist

A U.S. strike on an alleged drug-trafficking boat in the eastern Pacific killed one person and left two survivors, U.S. Southern Command said Tuesday night.

On social media, U.S. Southern Command said the boat was “operated by Designated Terrorist Organization,” was “transiting along known narco-trafficking routes” and was “engaged in narco-trafficking operations.” Video posted by the military showed a strike on a boat that appeared to break into two burning pieces.

U.S. Southern Command said it “immediately notified the U.S. Coast Guard to activate the Search and Rescue system for the survivors.”

The Trump administration began striking boats it says are trafficking drugs in Latin American waters, including the eastern Pacific and the Caribbean Sea, in early September. At least 193 people have been killed in the campaign.

President Trump has said the U.S. is in “armed conflict” with cartels in Latin America and has described the attacks as necessary to curb the flow of drugs into the U.S.

Trump has also pressed regional leaders to work more closely with the U.S. to target cartels and take military action against drug traffickers and transnational gangs that he says pose an “unacceptable threat” to the hemisphere’s national security.

The Defense Advanced Research Projects Agency is seeking proposals for robotic systems that could help treat and move wounded troops when battlefield medical care is overwhelmed during heavy combat.

In a Small Business Innovation Research solicitation, DARPA described an “autonomous, self-deploying, wound assessing, swarm-capable, self-linking, mobile robotic solution to assist reaching and moving casualties and perform life-saving interventions at the point-of-need.” The deadline is June 3.

DARPA said the current battlefield medical system, built around smaller counterinsurgency operations, may not meet the demands of large-scale combat. “Future Large Scale Combat Operations predict massive casualty incidents, delayed evacuation, and insufficient capacity of the medical system,” the agency said.

The solicitation said delayed treatment creates a “high chance of dying due to lack of hemorrhage control which is the leading cause of potentially survivable death in both battlefield and civilian trauma cases prehospital.” DARPA added: “We believe this is achievable due to the recent advancements in swarm, self-assembling, and mobile robotics, as well as robotics for medical applications.”

Any proposed system must meet at least two of four requirements. One calls for a robot able to drag an injured service member 10 meters onto a litter. If one robot cannot do so alone, multiple robots must be able to combine their strength.

DARPA also wants systems that can stabilize injuries during movement. The solicitation said multiple robots should be able to wrap around an injured limb, and swarms should be able to form tourniquets that would “self-arrange and reassemble into shapes to provide massive hemorrhage control.” The agency said the goal is to create a “smart tourniquet” that can autonomously clamp around injured limbs or apply pressure to a junctional wound.

In phase one, companies would demonstrate capabilities including swarming, injury identification, movement over rough terrain and across the human body, and “interlocking units, shape-changing, and rigid stability,” in a lab or on a medical manikin.

Phase two calls for a prototype for field testing using “perfused cadavers, animal models, or high-fidelity medical training phantoms,” along with a manufacturing plan that meets U.S. Food and Drug Administration requirements.

DARPA said the technology could also have civilian uses, including in collapsed buildings, fires, and hazardous chemical incidents where robots may reach casualties before medical teams can.
