The second round of UN-facilitated talks aiming to resolve Sudan's political crisis following a military coup has been postponed, a spokesman said Saturday, with a key civilian bloc still refusing to join.

Sunday's decision came after a meeting with senior military officials recommending the state of emergency be lifted and people detained under an emergency law be freed.

Burkina Faso became the fourth country to be suspended by the African Union after Guinea, Mali and Sudan to punish the coup leaders of these countries.

Sudanese security forces fired tear gas in Khartoum on Sunday at thousands protesting for civilian rule and against a military coup that took place last year.

Sudan anti-coup protesters faced tear gas at a democracy rally while General Abdel Fattah al-Burhan defended October's military takeover.

Sudanese anti-coup protesters plan to flood the streets Saturday to demonstrate against a military takeover that has derailed the country's transition to civilian rule and triggered a deadly crackdown.

Seven protesters have been killed in Sudan since a military coup four days ago, a health official said Thursday, adding that other bodies had since arrived without giving an exact number.

Taking a strong stance against the military coup in Sudan, Saudi Arabia and the US have condemned the overthrow of the government, and called for the immediate restoration of Sudan’s civilian-led transitional government.
