In Somalia's war-ravaged capital, Mogadishu, the BBC's Mohamed Mwalimu says more than 4,000 people are crammed into one camp, called Safety. Al-Shabab, an al-Qaeda-affiliated group which controls large swathes of south and central Somalia, had imposed a ban on foreign aid agencies in its territories in 2009, but has recently allowed limited access. UN Secretary General Ban Ki-moon said new funds to help the country were desperately needed. News International's parent company News Corporation has also confirmed it has stopped paying the legal fees of former private detective Glenn Mulcaire, who was convicted of phone hacking on behalf of the News of the World in 2007. US Secretary of State Hillary Clinton said on Wednesday that Washington would provide an extra $28m in emergency aid to counter the famine. In April 2010 US President Barack Obama issued an executive order naming al-Shabab a terrorist organisation, meaning no US aid could go to areas under its control, our analyst adds. The UK Secretary of State for International Development, Andrew Mitchell, said the response by many European and developed countries to the crisis in the Horn of Africa had been "derisory and dangerously inadequate".
