The Syrian state news agency SANA said Monday that “terrorists” killed a doctor in the country’s south, two military officers in the central province of Hama and two others in the south.

The Syrian government blames the uprising on terrorists acting out a foreign conspiracy.

The international community increasingly has used sanctions in an attempt to bring the Assad government to heel.

In Washington, President Obama announced new sanctions on people and entities in Iran and Syria that use technology to target citizens and erode their human rights. Iran has provided Mr. Assad’s regime with technology to jam cellphones and block or monitor social networking sites used to organize demonstrations.

“National sovereignty is never a license to slaughter your people,” he said.

In Luxembourg on Monday, the European Union passed its 14th set of sanctions against Syria, this time banning “luxury goods” and products that can be used against protesters.

EU experts will work out later precisely which goods will be listed in the embargo. A diplomat said they could include anything from vehicles to fertilizers and other chemicals.

The only precedent for the luxury ban is one imposed by the EU in 2007 on North Korea for its nuclear and ballistic missile programs, which included caviar and truffles, high-quality wines and spirits, fashion accessories, perfumes and purebred horses.

Officials said this could serve as a model for the same measures against Syria. Such a ban aims at the wealthy business class that largely has stood by Mr. Assad.

“We need to continue to intensify pressure on the Assad regime,” British Foreign Secretary William Hague said. “They are not in complete compliance with the cease-fire provisions of the Annan plan.”
