The statement added that Friday’s rockets proved once again that Iran is working to undermine the status quo in the region, and that they, alongside extremist organizations, are playing with the lives of Gazans and will lead to escalation after years of quiet.
On Saturday, Defense Minister Avigdor Lieberman said that Iran built and supplied the mortar shells fired at Israel Friday from Gaza by Salafist terror groups.
When asked whether Iran had transferred the shells to Hamas, which still controls the Strip, Lieberman said that Iran “supplied [them] to many in Gaza, it’s too early to say which.” Lieberman added that Israel has deterred Hamas from seeking a new conflict, but that Israel is losing its deterrence with radical Salafists supported by Iran. “They want to drag us into full-scale war,” he said.
