Sana'a: Yemeni President Ali Abdullah Saleh, who is being treated in Saudi Arabia for injuries sustained in an attack on his palace this month, is not likely to return to Yemen soon, a Western diplomat said on Thursday.

"We believe he was seriously injured ... He is not coming in the coming days, he is not coming soon," the diplomat said.

The diplomat told Reuters that a TNT bomb had been planted at the mosque, where Saleh was praying when he was injured on June 3.
