Ammon News - At least six Palestinians have been killed and 21 wounded after Israeli forces raided several areas in the occupied West Bank, Palestinian officials said.

Early Tuesday morning, large numbers of Israeli forces stormed the city of Nablus and were spotted by Palestinian security forces and armed fighters, according to a spokesperson for the Palestinian Fatah movement.

According to the Palestinian health ministry, five Palestinians were killed by Israeli fire. One of those killed was unarmed, Palestinian health and security officials said.

Their names are: Ali Khaled Antar, 26; Mishal Baghdadi, 27; Wadee al-Hawah, 31; Hamdi Qayyem, 30; and Hamdi Mohamed Sharaf, 35.

The ministry later reported that another Palestinian youth, Qusay al-Tamimi, was killed during confrontations with Israeli forces in the village of Nabi Saleh near the city of Ramallah, home to the headquarters of the Palestinian Authority in the occupied West Bank.

A spokesperson for the ministry told Al Jazeera that Tamimi was 19 years old.

The Israeli military said only that their forces were operating in Nablus but gave no further details.
