The Belgian prime minister met with organizations that operate against the Jewish state during his state visit to the country. Israel was quick to retaliate.

Prime Minister Benjamin Netanyahu, who also serves as Israel’s foreign minister, on Wednesday instructed the Ministry to reprimand Belgian Ambassador to Israel Olivier Belle.

The diplomatic incident was sparked following Belgian Prime Minister Charles Michel’s meeting earlier in the day with the extreme left-wing B’Tselem organization and anti-IDF Breaking the Silence during his state visit to the Jewish state.

Israel views the incident “with utmost gravity,” the Prime Minister’s Office said in a statement.
