A hate-filled taxi passenger smashed a Pakistani cabbie in the face with a skateboard after asking the driver his nationality, the driver said Tuesday.

Mohammad Ali Fahd suffered a fractured nose, facial cuts and swelling so severe he can’t open his left eye, authorities said.

Doctors don’t yet know how badly his vision will be affected.

“He was trying to kill me,” said Fahd, 36, a father of two. “I hope they catch this guy.”

The man hailed Fahd’s cab late Monday night on Second Ave. between Sixth and Seventh Sts.

Early in the trip uptown, the passenger asked Fahd his country of origin, then started cursing and banging on the partition when Fahd said he was born in Pakistan, Fahd said.

The outburst distracted Fahd and he hit a pothole, he said. The cab driver then pulled into a gas station at Avenue C and 23rd St. to assess the damage.

“I was doing my safety check to make sure everything was all right with the car when he came up and hit me from behind,” Fahd said.

An ambulance driver who was nearby chased the crazed passenger, who escaped on his skateboard, Fahd said.

A police spokeswoman said the attacker was an African-American man about 5 feet, 11 inches tall. He was wearing a white sweatshirt.
