Sydney Opal Tower: How could a crack form in a new building? Image copyright EPA Image caption The Opal Tower in Sydney opened to residents in July On Monday, Christmas Eve, hundreds of people were forced to leave their homes in a 38-storey tower in Sydney, Australia, when a huge crack was found in its wall.
Authorities later found the split in a support wall on the building's 10th floor. Engineers estimated it caused parts of the building to shift by up to 2mm.
Although nobody was injured, Australians were shocked by the fault in the newly-built Opal Tower in Sydney's Olympic Park.
The shiny high-rise boasted million-dollar apartments, and the developer and builder are well regarded in the industry.
The tower's construction and design has since been called into question, as have the standards of the wider Australian building industry itself.
Both the tower's builder and the developer defended the construction, saying that the temporary relocation was just a precau..

Anak Krakatau: How a tsunami could wipe out the last Javan rhinos Image copyright WWF Image caption The entire species of Javan rhinos could be wiped out by a tsunami They once roamed the jungles of South East Asia and India, but today only 67 of the critically endangered Javan rhinos still exist. They all live in one single place - the Ujung Kulon National Park - just miles away from the shadow of the volatile Anak Krakatau volcano.
When Anak Krakatau triggered a tsunami across the Sunda Strait, its effects were felt at the Ujung Kulon National Park (TNUK) in Banten.
Two park officials died, and numerous TNUK buildings and ships were also destroyed. But the 67 critically endangered Javan rhinos left in the park - the only ones left in the world - were left unscathed, for now.
The Javan rhinos typically live along the park's south coast. This time, the tsunami hit the north coast.
But the rhinos might not be so lucky if there is a next time, and now officials are rushing to move..

Image copyright Getty Images Image caption Many of the Rohingya now live in camps near the Bangladeshi border town of Cox's Bazar Throughout 2018, more than 700,000 Rohingya refugees fled from Myanmar to Bangladesh, following a military crackdown on the Muslim minority people.
Under a deal between the two countries, thousands of them were due to be moved back to Myanmar. But this was halted when none wanted to return. But what is in store for them should they chose they ever chose to go back?

But where Nelson Mandela's African National Congress (ANC) fought to dismantle an apartheid regime, Ms Suu Kyi's National League for Democracy (NLD) now stands accused of entrenching division and discrimination in her own blood-drenched country.

The BBC's Divya Arya reports.
Earlier this year, a video showing a group of teenage boys trying to rip the clothes off a young woman was shared extensively on WhatsApp in India.
