An Israeli airstrike Thursday killed two Palestinians in the northern Gaza Strip, and a Palestinian man fatally stabbed an Israeli soldier in the West Bank, intensifying a new round of violence touched off by a suicide bombing at an Israeli shopping mall this week.

An Israeli aircraft fired missiles at a group of suspected guerrillas from the al-Aqsa Martyrs Brigades in a house near the northern Gaza town of Jebaliya, Palestinian witnesses and health officials said. The strike killed Iyad Nasser, 27, and Iyad Qaddas, 21, and wounded six others, including an 11-year-old girl, hospital officials said.

The Israeli army said Qaddas had been involved in numerous attacks on Israelis, including suicide bombings.

Near the Qalandia checkpoint, a main crossing point for West Bank Palestinians entering Jerusalem, a Palestinian man stabbed an Israeli soldier in the neck and killed him. The attacker, from a village near Ramallah, was immediately arrested by soldiers.

With tensions rising, Israel suspended talks to open a road linking the West Bank and Gaza, just a week before the passage for Palestinians was to open. This drew angry criticism from the Palestinians, who accused Israel of violating an agreement brokered by Secretary of State Condoleezza Rice.
