A synagogue in the state of Washington was vandalized on Wednesday morning, KING 5-TV in Seattle reported.

Members of the Herzl-Ner Tamid Conservative Congregation, located in Mercer Island in the Seattle metropolitan area, found messages including "Shame" and "Shame on Israel" around the building, according to the report.

The Mercer Island Police Department was called to the synagogue to investigate. The FBI will lead the investigation, police later said.

Democratic House member Rep. Adam Smith condemned the vandalization in a post on X.

“The vandalism at Herzl-Ner Tamid is horrifying and heartbreaking. I condemn this atrocity and stand with the Jewish community in the Ninth District and across the country. Our Jewish friends deserve to feel safe – especially at their places of worship,” he wrote.

The vandalism comes amid a spike in antisemitic incidents in the US in the wake of the war between Israel and Hamas.

Earlier this week, the fence outside the Michigan vacation home of Obama-era White House Chief of Staff Rahm Emanuel was spray-painted with the word “Nazis.”

On Sunday, a grenade was found taped to a pole near a synagogue in Lakewood, New Jersey. It was removed by a bomb squad which was called to the scene.

Last week, headstones at a Jewish cemetery on Cleveland’s west side were found spray painted with red swastikas.

Previously, a Los Angeles woman was charged with hate crimes after ramming her vehicle through the gate of a local synagogue and cultural center.

In another incident, a 21-year-old student was charged with assault after he punched one person and slammed the thumb of another during a pro-Israel demonstration at New York University’s main library.
