Tel Aviv - Israeli troops left the Gaza Strip early Wednesday, hours after entering it in the most serious clash between the Israel Defence Force (IDF) and Palestinian militants since a ceasefire went into effect June 19.
The raid left six Palestinians - five militants and a civilian woman - dead, medical officials said.
A military spokeswoman in Tel Aviv said the troops went into the strip late Tuesday to destroy a 250-metre-long tunnel being dug under the border, which, she said, was being prepared to aid in the kidnapping of Israeli soldiers.
The operation was a "pinpoint" one, she said, to destroy an "immediate threat."
