A photographer could bear-ly believe his eyes when a bear started waving at him. The friendly animal wandered to the front of his enclosure before sitting back in full view of zoo guests. He then lifts his powerful paw and excitedly waves in an almost human-like way at his new audience. The hilarious encounter was captured by keen photographer Andrey Slepnev, 31, while on a trip to Madrid Zoo, Spain on March 24, 2016. (Photo by Andrey Slepnev/Caters News)

Young Lebanese women wearing protective masks and gloves against the coronavirus pandemic, stand on August 5, 2020 amid the rubble in Beirut's Gimmayzeh commercial district which was heavily damaged by the previous day's powerful explosion that tore through Lebanon's capital, resulting from the ignition of a huge depot of ammonium nitrate at the city's main port. Rescuers searched for survivors in Beirut after a cataclysmic explosion at the port sowed devastation across entire neighbourhoods, killing more than 100 people, wounding thousands and plunging Lebanon deeper into crisis. The blast, which appeared to have been caused by a fire igniting 2,750 tonnes of ammonium nitrate left unsecured in a warehouse, was felt as far away as Cyprus, some 150 miles (240 kilometres) to the northwest.
