The front-runner to succeed Chancellor Angela Merkel in Germany's September election has apologized for a scene in which he was seen laughing in the background as the country's president delivered a statement on the devastating floods in western Germany.

Iran PressEurope: Armin Laschet, the candidate of Merkel's center-right Union bloc to be Germany's next leader, is also the governor of North Rhine-Westphalia state — one of two badly hit by last week's floods. On Saturday, he visited the town of Erfstadt, which was the scene of a dramatic rescue effort after the ground gave way, with President Frank-Walter Steinmeier.

While Steinmeier gave a statement to reporters after the visit, Laschet and a group of others stood in the background. Photos showed him turning to someone else and laughing.

Flooding in western Germany has left 143 people dead and many missing.
