Six people were killed in the Gaza Strip when an Israeli missile exploded amid attempts to dismantle it.
The dead included two journalists - an Italian and a Palestinian - and a number of bomb disposal officers.
The incident happened in the town of Beit Lahiya, in the north of the Gaza Strip
It comes hours before a three-day ceasefire agreed between Israel and the Palestinians is due to expire.
Indirect talks aimed at finding a long-term solution to the Gaza conflict having been taking place in Cairo involving negotiators from the two sides.
Among those killed in Wednesday's explosion was Simone Camilli, a video journalist working for several international agencies, including Associated Press.
Some 2,000 people have died since the fighting in Gaza began on 8 July.
Those killed include more than 1,900 Palestinians, mostly civilians, according to the UN.
