MOGADISHU (Reuters/AFP) - Somalias govt resumed shelling insurgent strongholds in the capital on Saturday after a lull in its two-day-old offensive gave some residents a chance to flee. At least five civilians died and over a dozen wounded in the fresh fighting, witnesses said. One of my neighbours and two other civilians have died, said Asha Olow, speaking to AFP by telephone. Fighting is still going on in our neighbourhood. In southern Mogadishu, two others were killed when a mortar shell landed near a cafe in the Bakara area, an insurgent stronghold. We ran away from the area to escape the mortars which were falling randomly, said Farah Yusuf, another witness. Heavy fighting in Mogadishu on Friday killed at least 45 people. A local human rights group said more families left during Saturdays pause, joining 49,000 others who have fled the city during an upsurge of violence over the past two weeks. Residents said mortar shells hit the sprawling Bakara Market, the main Al-Shabaab stronghold in the city, and fighters clashed nearby. There were no details of casualties. Large numbers of families started fleeing today from new districts and this will deepen the already worsening humanitarian situation, Ali Yasin Gedi, vice-chairman of Elman Peace and Human Rights Organisation, told Reuters. Neighbouring states and Western governments fear Somalia, mired in civil war for 18 years, could become a haven for activists linked to Al-Qaeda unless the new government of President Sheikh Sharif Ahmed can defeat them. We shall continue the military operation against these anti-peace groups until Somalis get a long, lasting peace. We fought them and made progress in the latest operation, Information Minister Farhan Ali Mohamud told reporters. More than half of those killed on Friday were civilians and at least 182 people were wounded in the fierce clashes after pro-government forces launched a pre-dawn offensive. Al-Shabaab and other groups took up arms in 2007 to drive out Ethiopian troops propping up a Western-backed government which failed to wield control over much of the Horn of Africa nation. The Al-Shabaab, which Washington says has close ties to Al-Qaeda, and Hizbul Islam have been spearheading attacks on the capital and central Somalia. Somalias government has accused Eritrea of supporting Al-Shabaab fighters with planeloads of weapons including AK-47 assault rifles and rocket-propelled grenades. The African Union (AU) stepped up pressure on Eritrea on Friday by calling for UN sanctions, a no fly-zone and a sea blockade of Somalia to stem the flow of weapons. (The United Nations Security Council should) impose sanctions against all those foreign actors, both within and outside the region, especially Eritrea, providing support to the armed groups, the 53-member AU said in a statement. Eritreas president denies the allegation, saying US agents are spreading lies to blacken his governments name. Until Friday, pro-government forces had not looked strong enough to break Al-Shabaabs grip on parts of Mogadishu. Last weeks defection of a veteran warlord with hundreds of fighters may have prompted Ahmed to order the new offensive. Experts say pro-government forces will be hard-pushed to extend their reach to distant provinces, increasing the risk of protracted fighting in a country that has known little but violence and anarchy since its dictator was ousted in 1991. An important figure in any reconciliation would be Opposition leader Sheikh Hassan Dahir Aweys, who ran Mogadishu and much of southern Somalia alongside Ahmed in late 2006. Somalia has no government we recognise, Aweys told Reuters in an interview on Friday. We should not be deceived by Westerners like Sharif. We shall defeat the government soon, God willing.
