The Grammy winner played his first-ever show in the city on Wednesday.

Bruno Mars has canceled his second Tel Aviv concert after a surprise attack in Israel by Hamas on Saturday. The land, sea, and air assault, which took place on a Jewish holiday, led prime minister Benjamin Netanyahu to declare the country “at war” with the militant group, reports The New York Times.

“Dear customers, the performance of Bruno Mars that was planned to take place tonight is canceled,” Live Nation Israel announced in an Instagram statement in Hebrew, translated through Google. “All ticket buyers for the show will receive an automatic refund to the credit card with which the purchase was made. We are strengthening the residents of Israel, the IDF fighters, and the security forces in these difficult moments.”

Mars played his first-ever concert in Israel at HaYarkon Park on Wednesday. The following day, he posted a photo of himself facing the massive crowd on Instagram with the caption “Last night.”

Saturday’s attack left at least 250 people dead and 1,452 wounded in Israel, reports The New York Times. The outlet also reported that the Palestinian Health Ministry in Gaza said at least 198 people have died and at least 1,610 were wounded in the Gaza Strip following Israel’s subsequent retaliation.

“What happened today has not been seen before in Israel,” Netanyahu said, per the outlet. “We will win this war, but the price is unbearable.”\
