Israel on Sunday struck a mosque in the West Bank's Jenin, claiming that the building was being used as a command centre.
The strike hit the Al-Ansar mosque, with the army saying it had "neutralised" fighters, without specifying a number.
The Palestinian health ministry said two men were killed in the Jenin strike.
Elsewhere in the West Bank, a Palestinian was killed during a military raid of Nablus and another was shot dead in Tubas, the health ministry said in a series of statements.
The Israeli army could not immediately provide information about the Nablus and Tubas incidents.
Dozens of Palestinians have been killed in the West Bank by Israeli troops or settlers since October 7.
Israel has launched heavy bombardment of the Gaza Strip in retaliation, killing more than 4,300 people, mostly civilians, according to the Hamas-run health ministry.
