A Palestinian man abducted and killed an Israeli soldier whose body was found on Saturday in the north of the occupied West Bank, the military said.
An army spokesman said the soldier "was kidnapped and killed by a Palestinian near Qalqiliya yesterday (Friday) and his body was found" on Saturday.
The suspected killer was also arrested, the spokesman said.
Israel's internal security service Shin Bet said the suspect, a Palestinian from Beit Amin south of Qalqiliya, had confessed to killing the soldier.
The suspect said he had abducted and killed the soldier i the hope that he could trade the body in exchange for the release of his brother jailed by Israel in 2003 in connection with several attacks.
