Jerusalem: Despite U.S. President Donald Trump announcing a “complete and total ceasefire” between Israel and Iran, the Israeli military said early Tuesday it had identified missiles launched from Iran toward Israeli territory, triggering sirens across several areas.

“A short while ago, sirens sounded in several areas across Israel following the identification of missiles launched from Iran toward the State of Israel,” the Israel Defense Forces (IDF) said in a statement. “At this time, the IAF (Israeli Air Force) is operating to intercept and strike where necessary to eliminate the threat.”

Three people were killed after a missile struck a residential building in the southern Israeli city of Beer Sheva, CNN reported, quoting Israel’s emergency services.

According to Magen David Adom (MDA), the national emergency medical service, a man in his 40s, a woman in her 30s, and another man in his 20s were critically injured in the blast and later succumbed to their injuries.

An MDA spokesperson said six additional people were being treated for light to moderate injuries following the strike.

The escalation came nearly two hours after Iran’s 4 a.m. Tehran-time deadline, by which it had said it would halt further attacks if Israel stopped its military actions. Iran's foreign minister had earlier indicated that hostilities could end if Israel ceased strikes on Iranian targets.

However, the new missile activity raises questions about the viability of the ceasefire. The launches follow a limited Iranian missile strike on a U.S. base in Qatar, which Tehran claimed was retaliation for American airstrikes on Iranian nuclear sites.

Moments after Trump announced Iran and Israel had agreed to a ceasefire, the Israeli military launched a series of strikes on multiple locations in Iran, as claimed by Press TV, Iran's First International News Network.
