Heavy fighting broke out in the Somali capital Mogadishu, on Friday, around 16:00 local time, after faction leader Husayn Muhammad Aydid entered the former port. A battle between the opposition leader and militia guarding the port for the Transitional National Government (TNG) escalated into the bloodiest fighting experienced in Mogadishu over the last few years, and constitutes the biggest challenge yet to the interim government.
