Sheikh Sadiq Al-Ahmer, whose tribal supporters have been fighting the government forces in Yemen's capital Sana'a, has expressed his readiness to ceasefire if President Saleh accepts to do so.
Al-Ahmer told Aljazeera TV that he still dwelling in his home, heavily shelled by the forces in the last three days, as he urged the tribes of the most powerful tribal coalition in Yemen, Hashid, to hold, not to separate and not to hesitate to support their brothers.
Dozens have been killed and hundreds injured in the clashes in Al-Hasaba area that triggered fears a civil war has already begun.
The tribal fighters loyal to Al-Ahmer seized several government buildings.
Tribal and military mediations have failed to stop the battles, intensifying and expanding, as President Saleh continues to cling to power and ignore calls urging him to leave and start a peaceful power transfer immediately.
Saleh said on Wednesday that the forces were fighting saboteurs and destructive elements and if there was a civil war, it would be with those subversives seeking to kill the forces and take over public offices.
