The Trump administration has delayed a decision on lifting sanctions against Sudan by three months on Tuesday.

US President Donald Trump decided to amend the decision of the former President Obama by striking July 12, 2017 and inserting in lieu thereof "October 12, 2017".

"The Administration is committed to intensifying engagement with the Government of Sudan... including our ongoing dialogue on improving Sudan’s human rights and religious freedom practices," spokesperson Heather Nauert said in a statement.

Sudan's Foreign Minister Ibrahim Ghandour said on Monday that not lifting sanctions would be "illogical”, adding that Sudan had met all of the requirements needed to lift the sanctions.
