A new explosion rocked a refugee camp in the Gaza Strip, but no injuries were yet reported, according to Associated Press.
In the same time, Sa'ed Seyam, a senior Hamas leader stated the group will never lay down its arms.
His remarks come as a response to the visit of Palestinian leader Mahmoud Abas who arrived in Gaza on Wednesday for a discussion with the Islamic Resistance Movement.
Abbas will meet these days some of the leaders of Palestinian
factions to reach an agreement on keeping the truce with Israel and solving other important internal issues, as well.
Israeli Defense Minister Shaul Mofaz and Palestinian Interior Minister Nasser Youssef have finally reached another deal to coordinate the safe retreat of the Israeli troops from Gaza Strip in order to prevent the area from being taken over by Palestinian militants after the withdrawal.
The agreement comes to end the series of violent responses on both sides, just a few months after the two countries had agreed to a de facto ceasefire.
Palestinians asked for detailed information from their counterparts.
Giora Eiland, a senior adviser to the Israeli Prime Minister, Ariel Sharon, suggested last week that the military might have to enter Khan Yunis in southern Gaza in order to make safe the Gush Katif settlement block before the withdrawal set to start on August 15.
Israel will then begin the evacuation of the 21 Jewish settlements in the Gaza Strip and of 4 others of 120 built on the West Bank. If everything goes as planned, the withdrawal could take about a month.
