Summary Bahrain's opposition says National Guards were being deployed to quell rising political violence.
Wider use of the Guard could signal a tougher strategy by Bahrain s Sunni embattled monarchy as riot police struggle to contain the Shiite majority s 21-month uprising.
Hadi al-Musawi, a spokesman for Al Wefaq, says Guard troops were seen Saturday setting up in Sitra, a center of the revolt.
Previously, Guard forces separate from the regular military have been used mainly at key sites in the capital Manama.
Heavy clashes erupted Saturday after the funeral of a teenager killed in a traffic incident during a clampdown on marchers the day before.
More than 55 people have died in Bahrain s unrest.
