Botswana's president Tseretse Ian Khama has become the latest African leader to urge President Joyce Banda to forbid Sudanese leader Omar Al Bashir from entering the country during the July African Union summit.

Khama told the visiting Liberian president Ellen Johnson Sirleaf on Monday that Bashir had not shown any willingness to stop warring with South Sudan, hence democratic nations either arrest him or decline to host him.

"Sudan's president has been indicted to appear before the ICC for crimes against humanity and he plans to add more crimes with his continued war with South Sudan.

"It is for this reason that I request President Joyce Banda to deny him entry in July," Khama told Johnson Sirleaf.

Khama has been a fierce critic of Bashir's actions in Sudan, the latest being his condemnation of a silent declaration of war on the newly independent South Sudan over land and oil wells.

Bashir is wanted by the International Criminal Court (ICC) for alleged crimes committed in which issued a warrant of arrest in 2009.

But the AU heads of states meeting last week agreed that Malawi had no mandate to prevent Bashir from attending the AU summit.

This means Malawi will have the option of effecting the warrant of arrest which no other country, except Kenya has attempted to issue to hand Bashir over to the ICC.

Early this month, President Banda told the media that Malawi would not welcome Al Bashir to avoid straining its bilateral relations with donors willing to assist Malawi come out of its financial problems.

Local human rights organisations have also said they will disrupt the AU summit with protests if Bashir attends the summit.

Al-Bashir's attendance of the Comesa Summit in Malawi last year caused uproar in the international community as Malawi failed to arrest him as ICC demands.

This resulted into Malawi losing aid from various countries, including the suspension of a multi-billion energy aid package by the United States government.
