Jerusalem (CNN) -- Two suspects in the death of an Italian activist were killed Tuesday in a firefight with security forces in Gaza, Hamas said. A third suspect was wounded and taken to a hospital.
Security forces raided a house in the Nuserat refugee camp in central Gaza where the three men were believed to be hiding, according to the statement from the Hamas Interior Ministry. Hamas, a radical Islamic group, controls Gaza.
One of the suspects, identified as a Jordanian citizen, lobbed a grenade and then killed himself to avoid capture, Hamas said. The details of how the second suspect died were unclear.
In addition to the third suspect, three other people were injured in the incident.
The three men were wanted in the kidnapping and murder of human rights activist Vittorio Arrigoni, who was found dead last week in Gaza, hours after he was kidnapped.
Arrigoni, 36, had been active in the Palestinian cause for nearly a decade. He had been allied with the International Solidarity Movement for more than two years, "monitoring human rights violations by Israel, supporting the Palestinian popular resistance against the Israeli occupation and disseminating information about the situation in Gaza to his home country of Italy," the organization said in a written statement.
