US state trooper 'forced to shoot' man on US bus tour

A man who stabbed and injured two people on a US tour bus has been shot dead by police.

Connecticut State officers said they are dealing with a language barrier as they investigate the incident, which ended with the man being shot dead by police on the Interstate 95 route.

Another trooper is interpreting for the many Asian people who were on the Dahlia bus from New York City to Mohegan Sun casino on Tuesday night.

Authorities said the unidentified man attacked passengers with a “cutting instrument”, and the driver flagged down a trooper at a highway construction site in Norwalk.

Officials say the trooper and the man got into a fight, and the trooper was forced to shoot him. The trooper was unhurt.

A bullet fired by the trooper ricocheted and injured a third passenger. The three injured passengers’ conditions have not yet been released.

US airline stocks tumbled after news that the second health worker to be diagnosed flew on a commercial flight the night before reporting a fever.

Shares in the major American carriers were down between 4% and 6% in midday trading.

News of the second infection on US soil came three days after a nurse at the Texas Health Presbyterian Hospital, where Thomas Duncan - the first person to be diagnosed with Ebola in the US after flying in from Liberia - tested positive for the virus.

Nina Pham, 26, became the first person to contract Ebola within the United States, and the nurse’s infection raised questions about whether American hospitals and their staff are adequately prepared to contain the virus.

Mr Duncan died last week.

Ms Pham released a statement on Tuesday through Texas Health Presbyterian Hospital, saying she was “doing well,” and the hospital listed her as being in a good condition.

She has received a plasma transfusion from a doctor who beat the virus and the hospital CEO said medical staff members remain hopeful about her condition.

Ms Pham was in Mr Duncan’s room often, from the day he was placed in intensive care until the day before he died.

“I’m doing well and want to thank everyone for their kind wishes and prayers,” she said.

Ms Pham’s parents live in Fort Worth, where they are part of a close-knit, deeply religious community of Vietnamese Catholics. Members of their church held a special Mass for her on Monday. Her sorority sisters at the Texas Christian University held a candlelight vigil for her on Tuesday.

Ms Pham and other health care workers wore protective gear, including gowns, gloves, masks and face shields – and sometimes full-body suits – when caring for Mr Duncan. Health officials have said there was a breach in protocol that led to the infections, but they do not know where the breakdown occurred.
