A scorching heat wave across Pakistan's southern Sindh province has killed at least 622 people, authorities said Tuesday, as morgues overflowed with the dead and overwhelmed hospitals struggled to aid those clinging to life. According to AP, most of the deaths were reported in Karachi, the country's largest city and its commercial hub. The port city on the Arabian Sea had at least 600 fatalities. Temperatures reaching 45 degrees Celsius (113 degrees Fahrenheit) first struck over the weekend in Karachi, with mercury rising in the rest of Sindh province. Hours-long power outages, typical in Pakistan, left fans and air conditioners inoperable.
