SEOUL-South Korea reported its biggest jump in novel coronavirus infections in seven weeks on Wednesday, driven by a new cluster at an e-commerce warehouse on Seoul's outskirts, as millions more pupils returned to school.

The country has been held up as a global model in how to curb the virus and has rushed to contain new infections as life returns to normal.

But officials announced 40 new cases on Wednesday-taking its total to 11,265-with most new infections from the densely populated Seoul metropolitan area. It was the largest increase since 53 infections were announced on April 8.

An outbreak at a warehouse of e-commerce firm Coupang in Bucheon, west of Seoul, has seen at least 36 cases so far.

"It is suspected that the basic regulations were not enforced at the warehouse," said Vice-Health Minister Kim Gang-lip. "If quarantine rules are not implemented at workplaces, it could lead to a dreadful result of a mass infection."

In India, the country's coronavirus caseload has surpassed 150,000, with another single-day high of more than 6,000 reported on Wednesday. The spike comes as Prime Minister Narendra Modi's government prepares a new set of guidelines, with the fourth phase of the two-month lockdown across the country set to end on Sunday.

The country's health ministry had reported 151,767 cases as of Wednesday, a jump of 6,387, with 4,337 deaths-an increase of 170 in the latest 24-hour period.
