WASHINGTON (AP) - President Barack Obama says the United States is working with Britain to keep pressure on the government of Syria, strengthen the moderate opposition there and work to push for the end of the hardline regime of President Bashar Assad.
He called the violence there appalling and said western allies would work to strengthen the hand of moderate opposition to Assad's leadership.
Obama spoke at a White House news conference alongside British Prime Minister David Cameron. Their discussions touched on Syria's civil war, the Mideast peace process, a proposed free trade pact with Europe and next month's eight-nation economic summit in Northern Ireland.
Cameron is heading to Boston after his visit to honor those slain and wounded in the Boston Marathon bombing.
