The IDF on Sunday said it fired at a group of Palestinians flying incendiary balloons into southern Israel from the northern Gaza Strip. "But we need and I hope we will have the full cooperation of all Palestinians and all Israelis who are sick and exhausted of war and conflict, who want to live in peace, and who want to see their lives not constantly threatened by rockets or air strikes", Mr. Mladenov underscored.
"Particularly worrying is the impact that shortfalls in fuel will have on the provision of critical health, water and sanitation services in Gaza", U.N. deputy spokesman Farhan Haq said in a statement.

Israel has been warning Hamas that while it has no interest in exacerbating hostilities, it will not tolerate Gaza militants' continued efforts to breach the border and its campaign of incendiary attacks on Israeli border communities.
This step in only one in several other measures Israel has taken in the last few days to further strangulate an already hard-hit Gaza Strip, as confirmed by worldwide humanitarian agencies.
Israel and Egypt imposed a land, sea and air blockade on Gaza when Hamas reinforced its power over the territory in 2007 by ousting its rivals, a year after winning legislative elections.
Israel also warned that unless the balloons stop, it is going to escalate its punitive measures and also close Beit Hanoun (Erez) crossing for individuals.
Israel has tightened restrictions on its only cargo crossing with the Gaza Strip, after Palestinians carried out fresh attacks with incendiary balloons.

Hours later, Israel launched air strikes in Gaza.
Israel says its use of live fire is necessary to defend its borders and stop infiltrations.
The issue reportedly led to a debate between Israel's military chief of staff Gadi Eisenkot and far-right Education Minister Naftali Bennett during a security cabinet meeting on Sunday.
