A Palestinian gunman opened fire at a gas station near the Jewish settlement of Eli in the occupied West Bank Thursday, killing two Israeli men, the army and medics said.

"A short while ago, a terrorist arrived at a gas station in Eli and opened fire. The terrorist was neutralized," the army said, adding troops were pursuing other suspects in the area.

The incident occurred at the same gas station in Eli where four Israelis were shot dead by three Palestinian men in June last year.

Thursday's shooting came days after three Palestinian men killed one Israeli and wounded several others, including a young pregnant woman, near the Jewish settlement of Maale Adumim.

It came hours after the Israeli army massacred tens of Palestinians and wounded hundreds of others who were waiting on aid trucks west of Gaza City.

Since the Israeli war on Gaza broke out, Israeli troops and settlers killed at least 403 Palestinians in the West Bank, according to the Palestinian health ministry.

Israel has also arrested nearly 6,000 Palestinian youths in raids across the occupied territories.

Palestinian militants have also carried out numerous attacks against Israeli troops and civilians in Israel and the West Bank, killing at least 17, according to Israeli figures.
