JERUSALEM—At least two explosions were heard here after Iran launched a salvo of missiles in retaliation for Israel’s attack on the Hezbollah stronghold of Lebanon’s Beirut.

Air sirens were activated at around 5:53 a.m., triggering locals to seek shelter. Israel’s Home Front Command advised it was safe to go out after less than 10 minutes.

But at 7:01 a.m., another alarm was activated.

Manila Bulletin was in the Israeli capital for an event set this week, but confirmation whether that gathering will push through or not is yet to be made amid unprecedented developments.

Iran, for the first time since an April 18 ceasefire agreed on by Tehran and Washington, attacked Israel late Sunday night.

The move was in response to Tel Aviv’s bombardment of two apartment buildings in Beirut, where two people were killed.

"For Israelis, unfortunately, we learnt to expect it and not our first round of conflicts. So not completely shocked but you never get used to it," Nitzan Arny, an Israeli local, told Manila Bulletin, regarding his expectation of the situation. "We keep pushing for living our lives as normally as possible, maybe too optimistic."

Iran made its first attack on Israel in the north, in Haifa.

Social media videos showed Israelis cheering after Israel’s Iron Dome intercepted a missile in the skies. In a later statement, Israel said it intercepted all the missiles on Sunday night.

Early Monday morning, Tehran made another attack—a successive one—that targeted not only Jerusalem, where explosions were heard, but also Judea and the Dead Sea areas.

It was the first attack made on Jerusalem since the ceasefire took effect.

Meanwhile, the Philippine Embassy in Israel announced the suspension of consular activities as well as embassy operations on the same day.

“The Embassy will resume normal operations once updated guidance is issued by the Israeli authorities. Further announcements will be made accordingly,” it said.
