Israeli police are searching for a gunman who killed two people in an attack in Tel Aviv.

Spokeswoman Luba Samri says police remained on "heightened alert" Saturday. She says police and special forces searched for the shooter throughout the night.

The gunman opened fire outside a bar on a main street in Tel Aviv on Friday afternoon, killing two people and wounding at least three others before fleeing the scene.

Relatives of the shooter from the Arab village of Arara in northern Israel told media they recognized the man from CCTV footage aired on news reports.

Police say they are investigating possible motives for the attack, which came amid more than three months of Israeli-Palestinian violence.
