Palestinian police and Hamas gunmen were exchanging fire Saturday night in the West Bank city of Kalkilya after the security forces converged on a house where the Hamas men were barricaded and demanded that they turn themselves in, the Palestinian Ma'an news agency reported.
Palestinian security officials said that the policemen were surrounding the house in which two gunmen were entrenched.
Hamas's Al Aksa TV reported that police were attempting to arrest one of the organization's cells, which had planned to show its solidarity with the residents of the Gaza Strip by staging a demonstration.
According to Hamas, there were six people in the house, including Muhammad a-Saman, one of the most wanted men in the West Bank.
Hamas said that it held the PA responsible for the fate of its members.
