Police released a photo that appeared to show the vehicle after it had collided into the checkpoint.
Relatives identified the man as Ahmed Erekat, a 27-year-old owner of a printing shop. They said Erekat had rented the car as he prepared for his sister’s wedding party later Tuesday, and his own wedding was scheduled next week.
“There is no way on earth he would attempt to carry out an attack,” his cousin, Hiba Erekat, said.
In recent years, Israel has seen car-ramming attacks, shootings and stabbings carried out mostly by lone Palestinian attackers with no apparent links to armed groups.
But Palestinians and human rights groups have also accused Israeli security forces of using excessive force, or in some cases opening fire at cars that merely lost control.
Tuesday’s incident came as the Israeli government says it is advancing plans to annex parts of the occupied West Bank in line with the Trump administration’s Mideast plan as early as July 1.
