Former gang leader Duane ‘Keffe D’ Davis, 63, is accused of ordering the killing of the hip-hop star in 1996

A Las Vegas jury is now deliberating after hearing closing arguments in the trial of the South Side Compton Crips gang leader Duane “Keffe D” Davis, who is accused of ordering the murder of hip-hop legend Tupac Shakur.

Davis, 63, is accused of leading a group of men to kill Shakur in retaliation for the beating of his nephew, though not of pulling the trigger himself. Davis has pleaded not guilty.

Secretive state begins repairs on ageing facilities after being revealed as worst country for leaks of potent greenhouse gas

Turkmenistan has started plugging the mega-leaks of methane that spew from its ageing oil and gas facilities, the latest UN data shows, in a move hailed as a breakthrough.

Methane, also called natural or fossil gas, is a potent greenhouse gas. It traps 80 times more heat than carbon dioxide and causes 25% of global heating today. Stopping leaks can be quick and cheap and, because methane breaks down in the atmosphere far quicker than CO2, this has a rapid impact, with some experts calling it the climate “emergency brake”.
