AUSTIN, Texas (AP) — The Latest on deadly package bombings in Texas' capital city (all times local):

10:15 a.m.

Austin police say they have received more than 150 calls reporting suspicious packages after three package bombs exploded at homes in less than two weeks in the Texas capital.

The police department tweeted the figure Tuesday. Authorities have urged people receiving unexpected packages to call 911 without handling, moving or trying to open them.

A package bomb left on a doorstep in Austin killed a man March 2. Two similar packages left at separate homes Monday killed a 17-year-old and wounded two others.

Investigators originally suggested that the attacks could constitute a hate crime because the victims were all black or Hispanic, but they now say they are looking at all possible explanations.

The FBI and other federal agencies are also investigating.

Three package bombs left on doorsteps in suburban neighborhoods have exploded in less than two weeks in Texas' capital city, killing two people and wounding two others.

Police say the bombings in eastern Austin are likely linked. Two occurred Monday and one on March 2.

All the victims were minorities, and investigators are looking into whether race was a factor. However, they backed off initial suggestions that hate crimes could be a core cause.

The attacks unfolded as tens of thousands of visitors arrived for the busiest days of South By Southwest. The festival didn't appear related to the incidents.

People receiving unexpected packages in Austin are being urged to not handle them and to call 911.
