Three people were killed in a powerful explosion on a key bridge connecting Russia to Crimea

Ukraine’s post office released a new stamp commemorating the destruction of the Crimean bridge within hours of the alleged attack on it.

The brand features a drawing of two figures that resemble Hollywood stars Leonard DiCaprio and Kate Winslet locked in their iconic embrace from the 1997 film Titanic, shortly before the “unsinkable” ocean liner hit an iceberg and sank.

On the stamp, the two figures are standing on the edge of a ruined bridge. Smoke billows from its ruins behind them.

“The day has come: We announce a brand with a bridge,” said the Ukrainian Post.

The brand’s feed also includes a drawing of a fish swimming past a Russian road sign and a traffic light located on the seabed.

On Twitter, analysts speculated that the speed of the announcement of the new mark suggested that Ukrainian authorities were preparing to destroy the Crimean bridge, an important prestige project for Vladimir Putin.

Russia has blamed Ukraine for this morning’s attack on the bridge, but Ukrainian authorities have not claimed responsibility.
