Occupy Justice Malta has condemned the latest vandalism of the memorial to murdered journalist Daphne Caruana Galizia, saying the repeated attacks reflect a "continuity of hatred" and ongoing hostility towards peaceful protest.

Caruana Galizia's makeshift memorial at the Great Siege Memorial, located opposite the Law Courts in Valletta, was cleared and damaged again on Monday following Labour Party election victory celebrations in the capital, when Robert Abela was sworn in as Prime Minister.

In a Facebook statement, Occupy Justice said the memorial "has been cleared away, vandalised, burned, removed by force, mocked, and attacked countless times," but said that it endures because "memory remains there. Truth remains there. The demand for accountability remains there."

The group said the latest incident occurred "after celebrations of Labour's election victory" and accused what it described as the government's "continuity" of failing to protect the site.

"This afternoon, after celebrations of Labour's election victory, the memorial was vandalised once again. And we are told this government represents continuity," the post read.

The group said that the continuity of hatred towards Daphne Caruana Galizia, the continuity of intolerance towards peaceful protest, and the continuity of attacks on citizens who refuse to forget, has continued.

Occupy Justice also referred to a court ruling which found that the removal of the memorial breached freedom of expression, and questioned political claims that the Prime Minister governs "for everyone."

"For everyone? For the people who still gather peacefully to demand justice? For the activists who have maintained this memorial for over eight and a half years despite threats, insults, vandalism, and intimidation?" the group said.

The organisation said that democratic societies should not target memorials or peaceful protest sites.

"A democratic country does not fear flowers, candles, photographs, banners, or questions. A democratic country does not repeatedly attack the memory of a murdered journalist," it said.

Occupy Justice said it had already re-established the protest site and vowed to continue doing so despite repeated destruction.

"This memorial remains as long as justice remains to be served," it said, adding that "no vandalism, no slogan, no election celebration and no promise of continuity will change that."
