What happened
The blast struck one of Türkiye's leading steel producers at about midday on Monday, during work on an electric arc furnace at its Aliağa plant, an industrial and shipbreaking district about 60 kilometres north of İzmir. The explosion started a fire and left workers trapped beneath debris; onlookers said it felt like an earthquake. Relatives waited overnight outside the forensic institute for identification, which is being done by DNA analysis because of the victims' burns.
By Tuesday the investigation had widened into a criminal case: prosecutors sought 11 people, including the company's chairman, and a local court barred publication of reporting and commentary on the incident until the investigation ends. Labour unions and opposition parties have turned the blast into a national argument about workplace safety, pointing to two other fatal incidents at the same plant in the past three weeks.

Why this label: Agence France-Presse reporting from the scene, carried by Turkish Minute in two reports on Tuesday: the toll rose from 17 to 18 when search teams recovered the body of a worker who had been missing since the blast. Deputy Justice Minister Can Tuncay told reporters at the plant that the victims died from severe burns. The BBC reported the toll at 17 earlier on Tuesday, before the missing worker's body was recovered.
On the ladder: a claim earns Verified from primary evidence, or from two independent sources that do not copy each other.
Why this label: AFP via Turkish Minute, with the Northern Miner report of Deputy Justice Minister Tuncay's Tuesday briefing in agreement on the 11 warrants and the chairman. Whether the 11 warrants include the six people detained on Monday was not immediately clear in the reporting read.
On the ladder: a claim earns Verified from primary evidence, or from two independent sources that do not copy each other.
Why this label: The accounts are the officials' and the worker's own early statements, reported by AFP; investigators have not announced a cause, and the labour minister said it was too early to draw conclusions. HABAŞ declined to answer AFP's questions; the company has said it is working with authorities to establish the cause.
On the ladder: the evidence so far sits low — early, single or social sources. We publish the claim as a claim, never as fact.
Why this label: The ban and RTÜK's stated reasons, reported by AFP via Turkish Minute.

Why it matters
Industrial disasters test whether a country's safety system protects the people who work in its heaviest industries. With the plant's chairman detained, a reporting ban in force and unions and opposition parties demanding resignations and a parliamentary inquiry, how Türkiye investigates this blast — and what it is allowed to say publicly while it does — will be watched well beyond Aliağa.
Background
