Media caption Protesters and police clash outside Ukraine parliament Four people have been injured in clashes between riot police and demonstrators demanding major reforms in Ukraine's capital Kiev. The protesters are calling for an anti-corruption court to be set up, MPs to lose their immunity from prosecution, and changes to the electoral system. They vowed to stay on, putting up tents and blocking the main road outside the parliament building in central Kiev. One of the opposition leaders called for President Petro Poroshenko to quit.

Image copyright GETTY IMAGES British-Australian mining giant Rio Tinto and two of its former executives have been charged with fraud in the US, accused of hiding losses by inflating the value of African coal assets. It bought the Mozambique assets in 2011 for $3.7bn (£2.8bn) and sold them a few years later for $50m. The mining company has said it will "vigorously defend" the charges. The firm was also fined £27m by UK authorities for breaching disclosure rules over the African coal purchase. Both the US and UK actions relate to the Mozambique investment made by the mining firm six years ago. A lawsuit filed in the US accuses Rio Tinto, its former chief executive Thomas Albanese and ex-chief financial officer Guy Elliott of failing to follow accounting standards and company policies to accurately value and record the assets.

A seventh man managed to survive being stranded for about 12 hours in waters near the Queensland town of Seventeen Seventy, according to authorities.

A federal judge slapped a temporary restraining order on the open-ended ban before it could take effect this week. The policy targets Iran, Libya, Syria, Yemen, Somalia, Chad and North Korea, as well as some Venezuelan officials. Previous iterations of the ban targeted six Muslim-majority countries, but were checked by the Supreme Court. The state of Hawaii sued in Honolulu to block Mr Trump's third travel ban, which was set to go into effect early on Wednesday. It argued the president did not have the powers under federal immigration law to impose such restrictions. US District Judge Derrick Watson, who blocked Mr Trump's last travel ban in March, issued the new restraining order. ...
