Yemen tribal leaders deny link to palace attack on Saleh

SANA - The leader of a powerful Yemeni tribal federation on Friday denied his group was behind an attack on the presidential palace earlier in the day that injured several officials, his office said.
Sadeq al-Ahmar, head of the Hashed federation, blamed Yemeni President Ali Abdullah Saleh for the attack, saying it was done to help justify a government escalation of street fighting in the capital.
