For the first time since the lockdown, multiplexes have been permitted to open with 50 per cent seating. Schools and colleges, shut since March as lockdown was announced across the country, will be allowed to re-open from October 15, the Centre said on Wednesday while announcing the next phase of lifting of coronavirus-related restrictions. The final call, however, has been left to the states and the institutions involved. All international flights will remain suspended until October 31.
