ROME, 13th July, 2016 (WAM) — Italian Prime Minister, Matteo Renzi, has announced an immediate and thorough investigation into yesterday’s train crash in Puglia. Two passenger trains collided head-on in the incident on Tuesday morning, killing at least 25 people and injuring dozens more, some of them critically.

The crash occurred around 11:30 a.m. on a single track running through an olive grove between the towns of Andria and Ruvo di Puglia. The closest major city is Bari, about 20 miles east of Ruvo di Puglia.

The Prime Minister, who was attending the opening of a new science museum in Milan, said that he would return immediately to Rome and ordered an investigation. He later visited the site of the crash, the news agency ANSA reported.

“We won’t stop until we clarify what happened,” he told reporters in Milan. “There is an absolute need to understand who is responsible and to shed total light on what happened,” he said.
