AUSTIN, Texas (AP) - Police are responding to another explosion in Austin that badly injured a woman, hours after a package bomb killed a teenager and wounded a woman in a different part of the city.

  

Austin-Travis County EMS tweeted that an explosion Monday in southeast Austin injured a woman in her 70s, who has been hospitalized. A second woman from that address has been hospitalized with an unrelated medical issue.

  

Authorities have not said whether the most recent explosion was caused by a package bomb like the one that exploded earlier Monday.

  

Police Chief Brian Manley said at a news conference Monday that investigators believe the deadly blast Monday is linked to a March 2 package bomb that killed a 39-year-old man in another part of the city.
