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.

Verified
An explosion and fire tore through the HABAŞ iron and steel plant in Aliağa, İzmir province, shortly before midday on Monday 9 November, during maintenance work. Eighteen workers have died and 12 were injured, one of them critically.

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.

Verified
Prosecutors have issued detention warrants for 11 people, including HABAŞ board chairman Mehmet Rüştü Başaran and senior managers and technical staff. Başaran was detained in Istanbul on Tuesday and was to be taken to İzmir for questioning; six people had already been detained on Monday. Four prosecutors are assigned to the investigation.

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.

Not yet verified
What caused the explosion has not been established. Officials have given differing early accounts: the labour minister said falling material ruptured natural gas and oxygen pipes during maintenance; the energy minister said a crane collapsed during routine maintenance on an electric arc furnace; the İzmir governor described a boiler replacement operation; and a worker told AFP a crane cable broke, dropping about 120 tonnes of molten steel onto the furnace.

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.

Verified
An Aliağa court has imposed a publication ban on reporting and commentary about the blast until the investigation is completed; the broadcasting regulator RTÜK announced the order on Monday, saying its purpose was to prevent disinformation and protect public order and the investigation.

Why this label: The ban and RTÜK's stated reasons, reported by AFP via Turkish Minute.

On the ladder: a claim earns Verified from primary evidence, or from two independent sources that do not copy each other.

Verified
Labour groups have called protests over workplace safety in Aliağa, Istanbul and Ankara, and opposition parties are demanding accountability: the DEM Party called the blast a workplace killing and demanded ministerial resignations, and another opposition party called for a parliamentary inquiry. Two other workers died at the same plant in recent weeks — one in a fall on 21 October and one when a vehicle tyre exploded during inflation on 5 November.

Why this label: The protests, the parties' statements and the two earlier deaths are reported by AFP via Turkish Minute and by the Stockholm Center for Freedom. The parties' characterisations are their positions, not findings.

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

  • Explosion and fire at the HABAŞ Aliağa plant during maintenance work; the first tolls rose through the day as rescuers searched the debris.

  • Six people detained; RTÜK announces the court's publication ban on reporting about the incident.

  • The toll reaches 18 as a missing worker's body is recovered; prosecutors issue 11 detention warrants and the company's chairman is detained in Istanbul.
