Four Palestinians were killed in an exchange of fire after Israeli troops entered a West Bank refugee camp on Wednesday evening, residents said.
Witnesses said Israeli forces entered the Tulkarem refugee camp in the northern West Bank and surrounded a house.
After soldiers exchanged fire with gunmen in the house, Israeli jeeps entered the camp, and additional gunfire erupted.
The bodies of the four dead were brought to the Tulkarem hospital an hour after the incident. Residents said they were members of Islamic Jihad. Two other Palestinians were wounded, they said.
Israeli military officials said forces surrounded a house where armed militants were known to be hiding, and soldiers returned fire from the house.
The officials said the dead were senior members of Islamic Jihad involved in planning deadly suicide attacks in Tel Aviv in February and Netanya in July.
