LONDON — London's Royal Free Hospital says a nurse who recovered from Ebola last year is being treated for an unusual late complication of the infection.

A military aircraft flew Pauline Cafferkey from her home in Scotland to London early today. The hospital said she was being treated in its isolation unit.

Medical authorities say the risk of Cafferkey transmitting the virus is low, but public health officials in Scotland are monitoring people with whom she had close contact. Ebola is transmitted by direct contact with blood or body fluids.

Cafferkey was diagnosed with Ebola in December after returning from Sierra Leone. She was treated at the Royal Free for several weeks and discharged in January.

Cafferkey was honored at the Pride of Britain Awards in London last month and met with the prime minister's wife, Samantha Cameron, at 10 Downing St.

Since Ebola broke out in Guinea's forest region last year, it has killed more than 11,200 people in West Africa.

WASHINGTON — As many as four of the 26 long-range cruise missiles that Russia said it fired at Syrian targets landed instead in Iran, U.S. defense officials said Thursday.The officials said it's unclear whether the errant missiles, launched from Russian ships in the Caspian Sea, caused any significant damage in Iran. Both the Russian government and state-run Iranian media accused the United States of inaccurate or deliberately deceptive statements.Three U.S. officials said four missiles went off course.The Russian government said Wednesday it launched 26 cruise missiles, hitting targets in north and northwestern Syrian provinces. It made no mention of any missiles going astray, suggesting the operation was fully successful. The missiles' intended flight paths took them over Iran and Iraq.On Thursday, the Russian Ministry of Defense employed a little sarcasm in its denial.“However unpleasant and 'unexpected' it may be for our colleagues at the Pentagon and Langley about yesterday's attacks by high-accuracy weapons on the (Islamic State) infrastructure in Syria — all the same, all rockets fired from ships found their targets,” said a ministry spokesman.
