Yemen gripped by bloodiest uprising since 1994

Wednesday's moves promised to escalate the urban battle that has run for two days in the capital and appears to be the bloodiest in the country's four-month uprising. At least 37 people were killed in fighting Tuesday and Wednesday and dozens more were wounded, hospital officials in San'a said.

More fatalities were expected as fighting in San'a continued into the night, with explosions reverberating throughout the capital every few seconds early Thursday, reports Wall Street Journal.

"This is the worst fighting we have seen since 1994," when Yemen fought a two-month civil war, said one Yemeni official, who spoke on the condition of anonymity under diplomatic protocol. "And it's the worst fighting in Sanaa since the civil war of the 1960s", says  Pioneer Press.

"Saleh does not want peace," said the spokesman for the head of the Hashed tribe. "Saleh thrives with blood being spilt. They attacked us and we had to defend", according to CNN.
