JERUSALEM — Amid soaring tensions fueled by religious fervor and Palestinian anger over control of East Jerusalem, two drivers on Wednesday plowed their cars into Israelis in separate episodes, killing one police officer and injuring three soldiers.

The two episodes, in Jerusalem and the West Bank, have added to fears that a third intifada, or uprising, is taking shape as the latest crisis continues to reverberate beyond Israel’s borders. On Wednesday, Jordan recalled its ambassador to Israel, saying the move was for consultations and to protest “violations” at the most sensitive holy site in Jerusalem.

The Israeli police labeled at least one of the crashes a terrorist attack, in which a Palestinian affiliated with Hamas rammed a van into pedestrians in Jerusalem, killing the police officer and injuring at least a dozen other people. In the second episode, in the West Bank, a car with Palestinian plates ran over the three soldiers in what the military suspects was another deliberate attack; the driver escaped.

If the suspicions are correct, the episode would be the third time in two weeks that Palestinians used vehicles as weapons to harm Israelis.
