Israeli broadcaster Kan, citing an anonymous political source, is reporting that Netanyahu has decided to block the entry of mobile homes and heavy machinery into Gaza, Al Jazeera reports

“Following a security consultation chaired by the prime minister, it was decided that the issue of caravans will be discussed in the coming days. Israel is fully coordinating with the United States,” the source was quoted as saying.

The move, if confirmed, could again put the fragile ceasefire in Gaza under strain.

But Hamas went ahead with the release as planned on Saturday after mediators obtained from Israel a “promise … to put in place a humanitarian protocol” that would allow construction equipment and temporary housing into the devastated territory, according to AFP.
