Prime Minister Mette Frederiksen urged an overhaul of the international response to the conflict, which escalated as the Israeli army said it had launched a ground offensive against Hezbollah in southern Lebanon.

"There is no solution in sight to what we see going on over there, and there is no point in letting things continue," Frederiksen told Danish news agency Ritzau.

The two-state solution -- one Israeli, one Palestinian -- "can only be done if the international community declares, at some point, that we now have to impose it by force," she said.

Lebanese Islamist movement Hezbollah has for the past year been firing rockets at northern Israel in support of Palestinian militant group Hamas, which is at war with Israel in the Gaza Strip.

Israel has been retaliating against Hamas since the group's unprecedented attack on Israeli soil on October 7, 2023.

Frederiksen said Hamas and Israel "have caught not only their own countries and people in this, but all of us too".

"The price has become too high for all of us," she said.

Asked whether a military intervention was a possibility, she replied: "Yes, it's possible."

She remained vague however on how that could be accomplished.

"The international community has intervened in other conflicts and other wars and has succeeded in imposing something," she said.
