Prosecutors in Japan have filed formal charges against a US marine suspected of murdering and robbing a woman while stationed on the country’s island of Okinawa, according to Japanese media.

Devin Jacob Ballard, a 20-year-old lance corporal assigned to Marine Corps Air Station Futenma in Okinawa, is charged with fatally strangling Anna Yagi, 39, at a hotel in the city and stealing from her a backpack containing a wallet, the public broadcaster NHK reported.

Faced with a stagnant jobs market, many are spurning children or pets in favour of ‘raising bricks’

Young adults in China looking for a cheaper, low-maintenance alternative to having children or pets have found an answer: raising bricks.

The fifth plenum comes against a backdrop of years of purges that have had some analysts wondering if the issue is corruption or a lack of loyalty

When Xi Jinping came to power in 2012, he pledged to stamp out corruption all through the ranks of the Communist party. More than a decade later, the pace of investigations has not slowed. Last year, China’s disciplinary authorities opened investigations into more than 1 million people, including more than 100 officials at or above ministerial or provincial level.

As Chinese Communist party (CCP) officials kick off an important meeting this week, discipline – and party loyalty – is high on the agenda. For those who try to read the tea leaves of elite Chinese politics, concern about the apparent lack of discipline is dominating CCP discussions.
