Two separate explosions killed at least five civilians in the Somali capital, where the government is struggling to contain a lethal insurgency, witnesses said Friday. In one blast late Thursday, a gunman lobbed a hand grenade at tea shop in the Hurwa district. «The bomb went off among dozens of men,» said Muhiyadin Ga'amey, a witness. Three people were killed and five were wounded, he was quoted as saying by the Associated Press. Also Thursday, a land mine exploded in southern Mogadishu after a government convoy drove by, killing two people and wounding three, said Hussein Haji Jibril, who witnessed the blast.
