(CNN) -- At least nine people were killed in Somalia's war-torn capital Mogadishu when mortars slammed into a home for disabled veterans, according to journalists and witnesses.

At least 27 people were wounded in the Friday night incident, when Muslim militants fired mortars toward Mogadishu's port and struck a residential area. The mortars hit a home for former national army officers who were disabled in a late-1970s war with Ethiopia, the sources said.
Insurgents from the Al-Shabaab militant group have been fighting to topple Somalia's government. Its fighters have frequently shelled the city's airport and seaport, which are controlled by the African Union and government forces.
The United States is supporting the Somali government's fight against the insurgents, including providing weapons to government forces. Al Shabaab is on the U.S. list of terror organizations because of its ties to Osama bin Laden's al Qaeda network.
The United States is concerned that Somalia's weak government could fall to the Islamist insurgency, as it did in 2006 before Ethiopian forces ousted the militants from power later that year.

The Somali  (TFG), the internationally recognized government of the former state of Somalia, could not stop an attack conducted by insurgents in the capital as they shelled the city's port; but, some rounds fell short which led to dozens of casualties.

Late last week, Somali insurgents conducted a mortar attack in downtown Mogadishu missing their intended target at the city's seaport; instead, hitting a veteran's hospital killing between 6 and 9 former soldiers and wounding at least 12 others.  Many of the hospital's patients are veterans from  in the Ogaden, according to government spokesman Shiek Abdirisaq Qeylow.  The disabled veterans were gathering and chatting in the hospital's courtyard ready for the  (Futuru), the feast that breaks the dawn-to-dusk fast observed during the holy Muslim month of Ramadan, when the shells fell, according to the Associated Free Press.  Their home, De Martino Hospital, was collateral damage in what was meant to be an attack on the seaport according to Mohamed Abdiazis, a Somali Policeman.  Victims were taken to the Medina Hospital which is where four of the victims died.  Eyewitnesses said that several rounds hit the seaport and the main jail.  

Although no one has claimed responsibility for the attack, Al-Shabab, the militant youth group that has now taken the reigns of the insurgency in Somalia after the dissolution of the , is widely suspected.  Al-Shabab seeks to institute the strictest sense of Shari'a Law in Somalia and is a seam of contention for their participation in the government.  Earlier this year, the newly elected Somali President agreed to implement tenets of Shar'ia into the nation's statutory codes, however negotiations quickly broke down over the details.

While the TFG has made attempts to quell violence in the capital and in other parts of Somalia, little success has been realized.  The government relies on assistance from the African Union to maintain some semblance of order in Mogadishu.  Parts of the country like Somaliland in the north have claimed de-facto independence in the absence of a central government capable of protecting all parts of the country.
