Fadi Abu Zanat was killed early on Wednesday in clashes with occupation troops in Nablus, reported our correspondent.
Israeli forces stormed the Nur al-Shams refugee camp in the West Bank city of Tulkaram, destroying a home of a Palestinian activist.
The Israeli army detained eight Hamas activists overnight near the West Bank city of Ram Allah. They also seized three Palestinians wanted by Israel near Jenin and Nablus, according to Israeli military officials.
Elsewhere, Israeli troops blew up a tunnel in the Rafah area of the occupied Gaza Strip. Israeli military officials claimed it was being used to smuggle arms from Egypt.
An army spokesman said that 30 such tunnels had been located and destroyed in the Rafah area.
The fresh violence coincided with a US veto at the United Nations, put forward by Arab states demanding Israel should not harm or remove Palestinian President Yasir Arafat.
Last week Israel’s security cabinet said it would “remove” Arafat, without specifying what actions it may take. One Israeli official suggested Arafat should be assassinated, a proposal rejected by Washington.
