All 27 EU ambassadors to the Political and Security Committee endorsed adding 10 people, including Assad, to the sanctions list, EUobserver.com reported Wednesday. Thirteen members of Assad's regime already were on the register.
The committee also agreed on a statement, expected to be approved by EU foreign ministers Monday in Brussels, that threatens future financial sanctions.
Protesters for weeks have been calling for the ouster of Assad's government, which has responded violently in trying to quell the uprising.
"The EU is determined to take further measures without delay should the Syrian leadership choose not to swiftly change its current path," the draft approved Tuesday read.
The document includes provisions that would block new European Investment Bank lending to Syria, worth about $1.8 billion. The bank would still be obligated to honor existing contracts.
Haytham al-Maleh, an 80-year old Syrian lawyer and human rights activist, told EUobserver.com Wednesday the death toll is higher than the 700-plus figure quoted in most reports.
"Assad has already killed more than 1,000 people -- this is what all my contacts tell me," Maleh told the Web site by telephone. "I am collecting information by phone from all over the country."
