Israeli forces have killed a Palestinian man and razed houses on the second day of a raid on a Gaza Strip refugee camp, drawing vows of revenge from Palestinian militants.
An Islamic militant group urged Palestinians to unite and fight the Israeli troops, who have killed eight Palestinians since launching their open-ended raid on the Rafah camp to search for arms-smuggling tunnels under the Gaza-Egypt border.
The raid, the largest in months into Rafah, a known militant stronghold, followed a suicide bombing in Israel's port city of Haifa that killed 20 people last week.
An army spokesman said the army would stay in Rafah as long as necessary, indicating the raid would be open-ended - unusual for Israel which has recently staged only short-term operations in Palestinian areas.
Palestinian witnesses said the Israeli troops had razed at least 10 homes. The army said it had destroyed five roofless structures along with the homes concealing the three arms-smuggling tunnels its forces had uncovered.
Human rights organisations denounce house demolitions as collective punishment, Israel says they are a deterrent measure.
