South Africa President Kgalema Motlanthe hugs a Zimbabwean child upon his arrival in Harare on October 27, 2008. Leaders of a Southern African bloc gathered today in Zimbabwe to press President Robert Mugabe and the main opposition leader to break an impasse on forming a unity government. The security organ of the Southern African Development Community (SADC) organised the summit in Harare after Tsvangirai boycotted talks one week ago in Swaziland, to protest delays in receiving his travel papers from Mugabe's government.
