BEIRUT — Syrian troops recaptured from rebels Thursday a border town used by refugees to cross to Jordan, activists said, an apparent bid by the regime to stem the flood of Syrians fleeing their country's civil war.

Damascus meanwhile accused Cairo of stirring up violence in the country, as Syria lengthens the list of other Arab countries that it blames for its unrest. Egypt's President Mohammed Morsi called this week for Syria's president to step down in an indication of the increasing isolation of Damascus in the Arab world.

In the latest clashes, hundreds of Syrian soldiers backed by 20 tanks assaulted Tel Chehab, the Britain-based Syrian Observatory for Human Rights and local activist Mohammed Abu Houran said. Rebels fought back but were pushed out.
