Gun battles between troops and fighters leave dozens dead and wounded.
“Those behind the violence have distanced themselves from the Asmara alliance.”
The new group was created after a week of talks in the Eritrean capital by some 400 delegates ranging from Islamic courts leaders to former Somali government officials.
A spokesman in Asmara said it would push for the “liberation of Somalia” through military and diplomatic means.
In Mogadishu, Kulow said the interim government welcomed the formation of independent political parties.
“But we will never accept a terrorist alliance that wants to use violence to gain any progress,” he said.
The formation of the alliance is yet another bone of contention between long-time foes Ethiopia and Eritrea, and is likely to push back any prospect of desperately needed reconciliation in Somali politics, analysts say.
With 191 members of a central committee, the alliance includes well-known figures like Islamic courts leader Sheikh Sharif Ahmed and Hussein Aideed, a former deputy prime minister.
Analysts said the only possible upside from the alliance would be to provide a unified movement to negotiate with, should the international community be able to broker talks.

Meanwhile, in Somalia’s capital Mogadishu, the government announced on Thursday that a dusk-to-dawn curfew that had been in place for three months, has been lifted for the holy month of Ramadan.
The curfew has been in place since June, intended to help stop fighting between opposition fighters and the transitional government.
Somalis say the curfew prevented socialising, closed night businesses and prevented the wounded from reaching hospitals after nightfall.
