Donors have pledged 1.8bn euros ($2.4bn; £1.5bn) at a conference in Brussels to help Somalia end more than two decades of conflict.The money is part of a "New Deal" for what is widely regarded as a failed state, officials said.Al-Qaeda-linked al-Shabab dismissed the meeting as "Belgian waffle".Al-Shabab is fighting to oust Somali President Hassan Sheikh Mohamud's government, the first to be recognised by the US in more than 20 years.The group controls most of southern Somalia, but it has been driven out of the main cities and towns, including the capital Mogadishu, by an African Union (AU) force backing the government.The EU and Somali government believe now is a good time to adopt the programme as the country has entered a new era, with a more legitimate government and progress on the security front.Mr Mohamud told the BBC Somali service he welcomed the New Deal."It's a standard deal throughout the world in the post-conflict environment. This is a deal that is based on Somalia-led initiatives," he said.He said he would target four key priorities - security, legal reform, public finances and economic recovery, the AFP news agency reports him as saying.EU Commission President Jose Manuel Barroso said the extra money would support a "new phase in the life of Somalia".The EU would give 650m euros, while the rest would come from countries such as Denmark, Germany, Sweden and the UK, he said.The EU contribution would be in addition to the $1.6bn it gave Somalia from 2008 to 2013.Most of this money was used to finance the AU force of some 18,000 troops, AFP reports.Meanwhile, Uganda - the largest contributor to the AU force - has suspended 24 soldiers, including the mission head, on allegations of corruption.The UK's ambassador to Somalia, Neil Wigan, said the conference was "a major milestone", the agency says.The total of $2.4bn is more than double the amount diplomats were hoping to raise, it reports."Our combined efforts will maintain momentum and deliver the change that the people of Somalia desperately need," Mr Wigan is quoted as saying.The BBC's Abdirahman Koronto in Brussels says some Somali government officials were disappointed that most donor countries were represented by low-ranking officials.He says there is also some scepticism as previous pledges made at similar conferences have not been translated into improvements on the ground.'Slush fund'Al-Shabab said it expected donor pledges would remain mostly unfulfilled or the money would be lost in corruption."It's a bit like Belgian Waffles: sweet on the outside but really has not much substance to it," it said on its Twitter account.Mr Mohamud said at a news conference that aid money had been used to save lives, and provide basic services to Somalis.The New Deal would take Somalia from an "emergency to recovery" over the next three years, he said."This is a new chapter. Today we are ending a journey and starting a new one," Mr Mohamud added.There have been several international conferences to help Somalia rebuild itself, including one hosted by UK Prime Minister David Cameron in May.The UK and other donors pledged some $130m in aid for Somalia at the time.Earlier this month, Somalia's government said international investigators it had appointed had cleared it of corruption allegations made by United Nations monitors.In July, the UN Monitoring Group on Somalia said Somalia's central bank had become a "slush fund" for political leaders and that the current governor played a central role in irregularities surrounding unaccountable disbursements of cash.In September, Norway decided to directly pay government employees their salaries in order to curb corruption, UN-backed Somali Radio Bar-Kulan reported at the time.
