Iran warned Wednesday it is ready for any new Israeli attack, saying it has developed missiles with greater range and power than those used in their recent 12-day war.

"The missiles used in the 12-day war were manufactured ... a few years ago," Defense Minister Aziz Nassirzadeh said, quoted by the official IRNA news agency.

"Today, we have manufactured and possess missiles with far greater capabilities than previous missiles and if the Zionist enemy embarks on the adventure again, we will undoubtedly use them."

In mid-June, Israel launched a bombing campaign against Iran, triggering a war in which Iran responded with missile and drone strikes.

The Israeli offensive killed senior military commanders, nuclear scientists and hundreds of others, striking both military sites and residential areas.

The United States briefly joined the war with strikes on Iranian nuclear facilities.

A cease-fire between Iran and Israel has been in place since June 24.

Iranian officials have since warned that another round of fighting could erupt at any moment, emphasising that Tehran does not seek war but remains prepared for any confrontation.

On Monday, First Vice President Mohammad Reza Aref said Iran should be "prepared at every moment for confrontation."

"We are not even in a cease-fire; we are in a cessation of hostilities," he added.

Iranian media reported that the army is to begin a two-day military exercise Thursday, featuring a wide range of short and medium-range cruise missiles.

Western governments have repeatedly voiced concern about Iran's missile program, calling it a threat to regional security.

In July, France called for a "comprehensive deal" with Tehran that covers not only its nuclear program but also its missile program and its regional ambitions.

Iran has insisted that its military capabilities are not up for negotiation.
