The United States on Wednesday condemned what it called a "terrorist" attack by a Palestinian who rammed his car into pedestrians in Jerusalem, killing a baby, Al Arabiya reported according to Agence France-Presse.
"We express our deepest condolences to the family of the baby, reportedly an American citizen, who was killed in this despicable attack," State Department spokeswoman Jen Psaki said in a statement.
"We urge all sides to maintain calm and avoid escalating tensions in the wake of this incident," Psaki said.
Six other people were injured in the incident, which took place in the early evening, including a U.S. girl and her parents.
Israeli police called it a "hit and run terror attack" -- the second in the area in just under three months.
The driver later died from his injuries.
The violence came after months of tensions between Jews and Palestinians in east Jerusalem - the section of the city the Palestinians demand as their future capital.
The area has experienced unrest and near-daily attacks on the city's light rail by Palestinian youths since a wave of violence over the summer, capped by a 50-day war between Israel and Hamas militants in Gaza.
