Arsonists destroyed a car used by a senior Italian diplomat in Athens, prompting Italian Prime Minister Giorgia Meloni to express her “profound concern.”

Italian authorities said the official at the Italian embassy is Susanna Schlein, a career diplomat and the sister of the prominent Italian lawmaker Elly Schlein.

One car was destroyed, while a second vehicle suffered limited damage, when a crude incendiary device exploded in the garage of the diplomat’s home in the early morning on Friday in the garage of the diplomat’s house in a northern suburb of Athens. No one was hurt in the incident.

Meloni offered solidarity to the official and expressed “profound concern” and “sympathy.” The attack “was probably anarchist in origin,” she added in a statement.

“I am following the matter with the utmost attention,” Meloni said.

The attack was condemned by Italian Foreign Minister Antonio Tajani. “I called Susanna Schlein to express my solidarity,” he tweeted.

Tajani, who is expected in the Greek capital on Friday for the gathering of the European People’s Party, said he would meet with Greek Prime Minister Kyriakos Mitsotakis and visit the Italian embassy.

No group has so far claimed responsibility for the attack. It follows protests by Greek anarchist groups in support of a jailed Italian anarchist militant, Alfredo Cospito, who is on hunger strike protesting against prison conditions.

Greece’s Foreign Ministry condemned the attack. “This unacceptable and reprehensible action will in no way disturb the excellent relations and the long-standing bonds of friendship between Greece and its partner and ally, Italy,” the ministry said in a statement.

The Italian Foreign Ministry said in a statement that it was awaiting the results of a “thorough police investigation” and expressed its full solidarity and support to their colleague.
