Fresh blast injures woman in Texas following previous deadly explosions
An earlier blast which killed a teenager was linked to a March 2 explosion which killed a 39-year-old man.
Police are responding to another explosion in Austin, Texas, which left a woman badly injured, hours after a package bomb killed a teenager and wounded a woman in a different part of the city.
Austin-Travis County emergency services tweeted that an explosion on Monday in south-east Austin injured a woman in her 70s, who has been taken to hospital. A second woman from that address has also been taken to hospital with an unrelated medical issue.
Authorities have not said whether the most recent explosion was caused by a package bomb like the one which exploded earlier on Monday.
Police chief Brian Manley said at a news conference that investigators believe the deadly blast on Monday is linked to a package bomb on March 2 which killed a 39-year-old man in another part of the city.
