President Donald Trump has signed an executive order rolling Back Obama-era rules aimed at curbing climate change.

The President said this would put an end to the “war on coal” and “job-killing regulations”.

The energy independence executive order suspends more than half a dozen measures enacted by his predecessor, and boosts fossil fuels.

Business groups have praised the trump administration’s move but environmental campaigners have condemned it.

Outside the white house, a few hundred protesters gathered to vent their displeasure at the executive order.
