JERUSALEM (AP) _ A masked assailant killed an American university lecturer in the occupied West Bank on Sunday, police said.

The victim was Albert Ernst Glock, 67, head of the archaeology center at Bir Zeit Univeristy. The university has been closed for much of the 4-year-old Palestinian uprising. Military officials said it was a hotbed of violence.

A spokewoman, Tami Paul-Cohen, said police have no evidence the killing was political.

The assailant shot Glock after the archaeologist parked his car at the home of a research assistant near the university, 13 miles north of Jerusalem, said the spokeswoman.

''He was shot twice at close range,'' she said, adding that police were investigating the motive.

Glock was born in Gifford, Idaho, and lived in Illinois before coming to Bir Zeit in 1976, said university spokesman Mark Taylor. Glock lived in Aram, four miles north of Jerusalem.

Military sources said three 9mm bullet shells were found at the site and that Glock's body was taken to Abu Kabir Hospital for an autopsy.

''We are all in shock about this. He had been with us for many years and was well respected,'' Taylor said. ''I don't understand it. I have no doubt that this does not come from the Palestinians.''

Although Bir Zeit is officially closed, 2,000 students are taking classes off campus. Hanan Ashrawi, spokeswoman for the Palestinian delegation at Middle East peace talks, is an English professor at the university.
