Karachi, Oct 1 (IANS): Due to the emergence of at least 22 new coronavirus cases in Karachi, the Sindh government has imposed 'micro-smart lockdowns' in the provincial capital's Covid-19 hotspot areas.

On Wednesday, meanwhile, Karachi reported 221 cases out of a total of 311 in Sindh, according to provincial authorities, while the city has reported a majority of Pakistan's cases since the pandemic began.

According to Sindh Health Secretary Zahid Abassi new micro-smart lockdown was imposed in the city's UC-8, Manghopir and Gadap Town areas late Wednesday evening.

Under the new curbs, the entrance of unnecessary persons to the areas have been restricted, while residents were mandated to wear face masks.
