The US criticised the prolonged delay in oil exportation by South Sudan and Sudan on Tuesday, arguing that it undermines the peace process. Oil export has been delayed since the two states were unable to come to an agreement on how to withdraw their armies from the disputed border territories.

In a statement the spokesperson for the US State Department Victoria Nuland said:

The former head of the United Nations 2003 mission in Sudan has stated that aerial and ground attacks by Sudan's government forces in a border conflict with rebels may amount to war crimes.

A court in Johannesburg has convicted Nigerian militant Henry Okah of 13 terrorism counts, over a car bombing in Abuja in 2010.

Okah pleaded not guilty to the charges and denied being the leader of the militant group Mend, which claimed responsibility at the time.

A Bangladeshi court sentenced a Muslim cleric, Abul Kalam Azad, to death for crimes against humanity, committed during the war of independence in 1971.

The cleric, believed to be in Pakistan, was found guilty in absentia. The prosecution asserted he had shot dead six Hindus and raped Hindu women during the war.

The trial has drawn criticism however, with some saying the court is not endorsed by the UN and the charges brought against the cleric are politically motivated.

The three women, all activists linked to the PKK, were found on January 10 at an office, linked to the Kurdish movement.

The Colombian president Juan Manuel Santos has warned Farc not to return to violence once its unilateral ceasefire expires on Sunday.

The rebel group declared the ceasefire in November, ahead of peace talks, although the Colombian government refused to reciprocate the move and continued attacks on rebel positions.
