(CNN) -- Syria says results will be available Monday from its referendum on changes to the country's constitution, a vote taken as government troops continued pounding the opposition stronghold of Homs and other cities. Opposition activists reported at least 55 deaths across the country on Sunday, including 25 in Homs, which has been under bombardment for more than three weeks. Despite the ongoing violence, it held a vote on what the government of President Bashar al-Assad calls a move toward reform. Interior Minister Mohammed al-Shaar said the voting ran "normally" in most provinces, and turnout was "huge ... except in some areas," the state-run Syrian Arab News Agency reported. Results from the vote would be announced Monday evening, SANA said.
