Somali Interior Minister Abdi Shakur Sheikh Hassan has been killed in a suicide attack at his home in the capital Mogadishu, officials say. The bomber appeared to be a woman, an official told the BBC. Militants who control much of Somalia have carried out suicide attacks in recent years. Meanwhile, two people are said to have been killed in Mogadishu during protests against a deal to extend the terms of the president and parliament. Under the deal signed in Uganda on Thursday, their mandates have been extended until June 2012. Elections had been due this year. The prime minister is to be sacked and a new one appointed within 30 days. Friday saw a second day of demonstrations against the deal, and in support of Prime Minister Mohamed Abdullahi Farmajo. Witnesses said troops fired on protesters who had gathered outside the hotel where MPs have been meeting, killing two. No groups has claimed the bombing in which Sheikh Hassan died. It was the third suicide attack in Mogadishu in less than two weeks. Pro-government forces have been gaining ground in the capital. African Union troops have seized territory from al-Shabab, the al-Qaeda linked group. However, al-Shabab still controls much of southern and central areas of the country. Somalia has been racked by constant war for more than 20 years. Its last functioning national government was toppled in 1991. Source: BBC
