Israel’s military chief on Monday said that the country will respond to Iran’s weekend attack. However, he did not elaborate on when and how as world leaders urged against retaliation.

Israeli military chief Lt. Gen. Herzi Halevi said that Israel is considering its next steps but that the Iranian strike “will be met with a response.

The army’s spokesman, Rear Adm. Daniel Hagari, said Israel will respond “at the time that we choose.” Both men spoke at the Nevatim air base in southern Israel, which Hagari said suffered only light damage in the Iranian attack.

Iran launched hundreds of drones, ballistic missiles and cruise missiles at Israel on Saturday. The Israeli military said that 99% of the drones and missiles were intercepted, by Israel’s own air defenses and warplanes and in coordination with a U.S.-led coalition of partners. It marked the first time Iran has launched a direct military assault on Israel despite decades of enmity dating back to the country’s 1979 Islamic Revolution.

In a conversation with US House Majority Leader Steve Scalise, Israeli PM Netanyahu said that “Israel will do whatever is required to defend itself,” the prime minister’s office announced.

While Israeli leaders have hinted at retaliation, the government is under heavy international pressure not to further escalate the conflict — especially after the Iranian strike caused such little damage.

The US has urged Israel to show restraint as it seeks to build a broad diplomatic response.
