Explosion near Chabad House in Santa Monica (updated)

From LA Times blog:

A device believed to be a pipe bomb exploded about 6:45 a.m. Thursday in the parking lot of a Jewish temple in Santa Monica, authorities said.

No details were available regarding injuries or damage.

The incident occurred at a synagogue near 17th Street and Broadway in Santa Monica. Police evacuated a four-block area and were investigating the possibility of a hate crime.

[Updated at 9:50 a.m.: Multiple sources familiar with the investigation said the device exploded just north of the temple. Authorities were trying to determine whether the temple in the 1400 block of 17th Street, Chabad House of Santa Monica, was specifically targeted.

There were no reports of injuries.

The FBI, Los Angeles Police Department bomb squad and Santa Monica Police were all on scene.]

UPDATE:

An explosion that sent an object hurtling onto the roof of a home near a Jewish school and prayer house on Thursday was an accident — not a bomb, police said.

Sgt. Jay Trisler said a mechanical failure caused a pressure buildup resulting in the blast at about 6:45 a.m. Thursday.

UPDATE: It was a bomb, and it looks like it was set off by a Jew. More at YWN.
