Yemen President Ali Abdullah Saleh returns to Sanaa

Yemen TV said President Saleh arrived in the capital, Sanaa, by private plane at dawn. No other details were given.

He went to Saudi Arabia in June for treatment following a rocket attack on the grounds of the presidential palace.

President Saleh, who has been in power for more than 30 years, has faced months of protests urging him to quit.

Correspondents say his return raises the risk of all-out civil war.

"We're definitely going to have an escalation of violence, but let him come back - we want him to come back and be tried for his crimes," said protest organiser Mohammed al-Asl.

Activists have been camped out in Sanaa's Change Square since January demanding an end to his rule.

Clashes in the capital between government troops and forces opposing the president have recently intensified.

More than 80 people, mostly unarmed protesters, have been killed since Sunday.

Medics say at least one person was killed overnight and many others wounded when mortars landed in Change Square; Kazinform cites BBC.
