A powerful tsunami generated by an undersea earthquake killed more than two dozen people and wiped out several villages in the tropical islands of American Samoa and Samoa early on Tuesday there, according to officials and local residents who were working to assess the damage.
An 8.3-magnitude quake struck at 17:48 GMT, generating 4.5m waves in some areas of Samoa and American Samoa. The Samoa islands comprise two separate entities - the nation of Samoa and American Samoa, a US territory - with a total population of about 250,000 people. A tsunami warning was issued, but it has now been cancelled.
