A blaze on Thursday at one of Egypt’s main telecommunications hubs was extinguished, days after a larger fire there killed four people and disrupted internet, transport and banking services.

Four workers were killed and at least 22 others were injured in a fire that broke out on Monday at a key data centre in Cairo, Hossam Abdel Ghaffar, the spokesperson at Egypt's Health Ministry, told Reuters on Tuesday.

Officials in Egypt's capital say a fire has engulfed a telecom company building in downtown Cairo, injuring at least 14 people and prompting a temporary outage of internet and mobile phone services.
