WASHINGTON — As American authorities search for answers into mysterious ‘‘health attacks’’ that began two years ago in Havana, US and Cuban officials on Thursday renewed efforts to determine the method and motive behind incidents that have left some diplomats with brain injuries.

Talks at the State Department on Thursday came as national security agencies and members of Congress express frustration about the lack of answers about what the United States says were deliberate attacks on some two dozen staffers at the US Embassy in the Cuban capital.

Cuba’s foreign ministry said the scientific team it assembled to look into the incidents met with US lawmakers and the National Academy of Sciences before the talks.

Twenty-five US Embassy workers in Cuba, as well as one at the US consulate in Guangzhou, China, have been affected by mysterious health incidents that began in the fall of 2016. The range of symptoms and diagnoses includes mild traumatic brain injury, also known as concussion.

The last case from Havana was confirmed in June.
