A Facebook group on Sunday called for a "Week of the Martyrs" protest in Syria to honour those killed in a security clampdown on pro-reform rallies.
"The Week of the Martyrs will be a thorn on the regime's side," the organisers of Facebook group Syrian Revolution 2011 said.
The group unveiled its protest plans ahead of a mass turnout at the funeral in Douma, a suburb north of Damascus, of eight people killed during a security forces crackdown on the Muslim sabbath.
It trumpeted fresh protests on Tuesday, especially in towns "far from the capital," designating Jabla and the coastal cities of Tartus and Latakia as protest centres.
The group also pushed for a Wednesday boycott of mobile phone companies after Syriatel and MTN rewarded customers with one free hour in recognition of pro-regime ralliers.
And the rallying call for Thursday took aim at the ruling Baath party, in power since 1963, setting its headquarters as the protest point.
Meanwhile, the state-run news agency SANA said Syrian President Bashar al-Assad had tasked a former minister with forming a new government.
The sacking of the previous cabinet and a presidential speech on Wednesday failed to quell pro-reform demonstrators anxious for an end to the state of emergency in place almost 50 years.
Activists on Saturday said 46 people were detained in a wave of arrests at protest hubs including Douma, the southern tribal town of Daraa and the northern industrial city of Homs.
