Hungarian far-right leader Krisztina Morvai has blasted Israel's offensive on the Gaza Strip, calling it a "mass murder" and "genocide of the Palestinian people."

In an open letter to Israel's ambassador to Hungary, Morvai, who heads the rightist Movement for a Better Hungary, wrote that Israel held itself "above the law." She expressed her belief that Israeli leaders will be imprisoned over their actions in Gaza.

Morvai added that she "rejoiced" when she heard of Israeli casualties in Gaza.

Addressing Israelis, the Hungarian politician lashed out, saying: "The only way to talk to people like you is by assuming the style of Hamas. I wish all of you lice-infested, dirty murderers will receive Hamas' 'kisses.'"

Morvai is an associate professor of law in Budapest.

The far-right Movement for a Better Hungary is slated for election in the European Parliament.
