Fire in Korangi Creek Karachi extinguished after 18 days
Listen to article
The unabated fire that raged for over two weeks in Karachi's Korangi Creek area has finally been extinguished, concluding a 18-day episode that drew widespread attention.
The blaze, which began on 29 March following a 1,200-foot-deep borehole drilling, raised serious concerns about the nature and volume of underground gases fuelling it.
Although the flames have subsided, gas emissions continue from the pit, causing water — initially used by firefighters — to erupt at the site. The situation remains unstable, with hot water and visible vapours still emerging from the ground.
In response, the Ministry of Petroleum established a special committee to test for methane gas and consulted Cudd Well Control, a US-based global expert in emergency well response.
Technical teams from Pakistan Petroleum Limited (PPL) and United Energy Pakistan Limited conducted a joint visit, noting that the fire's intensity had remained unchanged for days, indicating a potentially significant underground gas reserve.
The crater has widened due to sand displacement and overflowing water. Preliminary chemical analysis of the water from the site has revealed dangerous levels of chemicals, including benzene, toluene, tetrachloroethylene, and o-xylene.
Tetrachloroethylene was recorded at 33 µg/L, far exceeding the safe limit of 5 mg/L. Benzene levels reached 19 mg/L — nearly four times the permissible amount — while toluene was found at 15 µg/L.
Although hydrocarbons were within allowable limits, experts warn that the presence of these hazardous substances poses ongoing environmental and health risks.
Further investigations are underway to assess long-term hazards and identify the exact source of the gas leak.

HRW warns Gulf labourers at risk as temperatures soar
BEIRUT: Human Rights Watch said Sunday that migrant workers in the Gulf were at risk from extreme heat, urging countries to extend protections for labourers exposed to soaring temperatures. The United Arab Emirates, Saudi Arabia, Qatar and Kuwait, where migrants represent a sizable share of the workforce, lie in one of the planet's hottest regions where summer temperatures often edge towards 50 degrees Celsius (122 degrees Fahrenheit). 'Every summer reveals that the climate crisis aggravates the occupational health and safety catastrophe for the millions of migrant workers dangerously exposed to extreme heat,' said Michael Page, HRW's deputy Middle East director. 'Because Gulf states are dragging their feet on evidence-based labour protections, migrant workers are unnecessarily dying, experiencing kidney failure, and suffering from other chronic illnesses,' he added. The wealthy Gulf states rely heavily on millions of migrant workers particularly in construction, the majority of whom hail from India and Pakistan. Last month, the UAE breached its May temperature record for the second day in a row, hitting 51.6 degrees Celsius. To protect labourers, the states ban work under direct sunlight and in open-air areas at peak heat hours from mid-June until mid-September as part of a longstanding 'midday break' policy. But with the Gulf particularly vulnerable to climate change, HRW said 'these extreme heat conditions are now more frequent and earlier, in May', before the midday break comes into effect. A electrician in Kuwait interviewed by the New York-based rights group said he would feel 'dizziness, vomiting, head pain, and blurry vision many times,' working during the summer months and 'many people fall down because of heat'. HRW urged authorities and businesses to move away from 'calendar-based midday bans,' to risk-based measures to gauge occupational heat stress. Scientists have shown that recurring heatwaves are a clear marker of global warming and that these heatwaves are set to become more frequent, longer and more intense. The number of extremely hot days has nearly doubled globally in the past three decades. According to a 2024 report from the International Labour Organization, a United Nations agency, outdoor workers in Arab states face some of the highest exposure to heat stress in the world, with 83.6 percent suffering from excessive heat exposure on the job.

Paris wheat pushed down by export-punishing euro strength
HAMBURG/PARIS: European wheat futures eased for a third straight session on Monday as a firmer euro reinforced export concerns while recent weather worries subsided. Volumes were light, with a holiday closure in Chicago depriving Euronext of its usual impetus. Benchmark September milling wheat on the Paris-based Euronext fell 0.7% to 205 euros ($233.27) a metric ton at 1516 GMT. The contract continued to move away from last Wednesday's one-month peak of 213 euros and drift back towards a contract low of 201 euros struck two weeks ago. Wheat rallied early last week as concerns over adverse weather in Russia and China encouraged short-covering by speculators. But traders have since played down the risk of significant crop damage while weak export demand has also cooled the market. The euro rose to a one-month high against the dollar. 'The euro is weighing a touch today,' a futures dealer said. The European Union's crop monitoring service MARS increased marginally its outlook for this year's soft wheat yield in the European Union, citing beneficial rain in southern Europe and limited effects so far from a prolonged dry spell in northern Europe. 'There is very little demand in the market, with the Black Sea seeming to receive what purchase interest is present,' one German trader said. 'Overall, importers expect good crops in Russia, Ukraine and the EU and are waiting for harvest-time downward pressure on prices.' Substantial rain fell in drought-hit north German wheat regions over the weekend, calming fears of dryness stress to crops. 'The big immediate fear about dryness damage has been removed,' another German trader said. 'But much of north Germany has only received about 30% of its normal rainfall so far this year. Overall, north Germany still has a water deficit and more rain is needed in coming weeks.'

India's monsoon rains arrive 8 days early, earliest in 16 years
Monsoon delivers 70% of India's rain, vital for farms and economy; half of farmland relies on June-Sept rains. PHOTO: PEXELS Listen to article Monsoon rains hit the coast of India's southernmost state of Kerala on Saturday, eight days earlier than usual, marking the earliest arrival in 16 years and providing the promise of a bumper harvest and relief from a gruelling heatwave. The monsoon, the lifeblood of the country's $4 trillion economy, delivers nearly 70% of the rain that India needs to water farms and replenish aquifers and reservoirs. Nearly half of India's farmland, without any irrigation cover, depends on the annual June-September rains to grow a number of crops. Summer rains usually begin to lash Kerala around June 1 before spreading nationwide by mid-July, allowing farmers to plant crops such as rice, corn, cotton, soybeans and sugarcane. The onset of the southwest monsoon over Kerala on May 24 is its earliest onset since May 23, 2009, the India Meteorological Department (IMD) said on Saturday. The monsoon has covered Kerala and parts of neighbouring Tamil Nadu and Karnataka, as well as parts of the northeastern state of Mizoram, the IMD said. At least 14 dead due to heavy rain in India's Gujarat Conditions are favourable for the monsoon's further spread into Goa, parts of Maharashtra, Andhra Pradesh, the northeastern states, West Bengal, and the remaining parts of Karnataka and Tamil Nadu over the next 2 to 3 days. Surplus pre-monsoon rainfall and an early monsoon onset will help farmers, especially in the southern and central states, to sow summer crops earlier than usual, said Ashwini Bansod, vice president for commodities research at Phillip Capital India, a Mumbai-based brokerage. 'Abundant soil moisture and early sowing could potentially boost crop yields,' Bansod said. Last year, the monsoon reached the coast of Kerala on May 30, and overall summer rains were the highest since 2020, supporting recovery from a drought in 2023. The IMD last month forecast above-average monsoon rains for the second straight year in 2025. The department defines average or normal rainfall as ranging between 96% and 104% of a 50-year average of 87 cm (35 inches) for the four-month season.
