The United States and the European Union warned Tuesday that they will within days take further punitive steps against Syria over its deadly crackdown on pro-democracy protests, as France said the U.N. Security Council is close to achieving a majority for a resolution to condemn the repression.

The warning came as diplomats in Brussels told Agence France Presse that EU ambassadors were due to decide Tuesday whether to add President Bashar al-Assad's name to a list of Syrian officials targeted by a travel ban and assets freeze.

Half of Kuwait's MPs urged the government on Tuesday to sever ties with Damascus and expel its ambassador in protest at Syria's deadly crackdown on anti-regime demonstrators.

Twenty-five out of 50 MPs called on the Kuwaiti government to "cut ties with the repressive (Syrian) regime and to expel its ambassador in Kuwait," in a statement received by Agence France Presse.

An Israeli deputy minister is to meet members of the Syrian opposition in the offices of Austria's far-right Freedom Party (FPOe) in Vienna later on Tuesday, an FPOe spokesman revealed.

The Israeli official is Ayoob Kara, deputy minister for development of the Negev and Galilee, and he will meet five Syrian opposition members, the names of whom were not revealed, said spokesman Karl-Heinz Gruensteidl, confirming a corresponding report in the tabloid daily Oesterreich.

Syria's opposition called for a general strike Wednesday in defiance of a government campaign to crush pro-democracy protests, as the army pressed its siege of the restive town of Tall Kalakh, the latest target of its violent crackdown.

"Wednesday will be a day of general strike in Syria," said a statement posted on the Facebook page of the Syrian Revolution 2011, an Internet-based opposition group that has been a motor of protests that erupted two months ago.

Italian Foreign Minister Franco Frattini drew a distinction between Syrian President Bashar al-Assad and Libyan leader Moammer Gadhafi, saying Assad had proposed reforms and played a strong diplomatic role.

"Assad made promises for reforms that he didn't keep. Gadhafi never promised reforms," Frattini said in an interview with Corriere della Sera daily.

Britain summoned Syria’s ambassador Friday in coordination with other EU nations to warn of fresh sanctions against the regime if it fails to stop a crackdown on protesters, as Turkey's premier said it was premature to say whether President Bashar al-Assad should quit.

In a statement, the Foreign Office said it had "called in the Syrian Ambassador Dr. Sami Khiyami ... to express the UK’s strong concerns about the ongoing situation in Syria."

At least five people were killed in Syria, activists said, despite an order from President Bashar Assad for security forces not to open fire on protesters and an offer of dialogue.

Friday's bloodshed cast a pall over the government's pledges to forge ahead with reforms in Syria, which has been gripped by two months of deadly protests.

Russian Foreign Minister Sergei Lavrov warned Friday against foreign intervention in Syria, calling on the Syrian opposition not to seek a repeat of the "Libya scenario".

"We are very worried that the process of reconciliation, the process of the start of dialogue ... is being slowed down by a desire of some participants to attract foreign forces to support their actions," Russian news agencies quoted Lavrov as saying.

Syrian security forces and unidentified gunmen killed at least 19 civilians on Wednesday, as authorities pressed a deadly crackdown on protest hubs across the country, human rights activists said.

Among the dead was an eight-year-old boy, the head of the National Organization for Human Rights in Syria, Ammar Qurabi, told Agence France Presse.

Syria's security forces shot dead 30 people Friday, a Syrian human rights activist told the AP, as thousands rallied on a "Day of Defiance" against the regime of President Bashar al-Assad after tanks converged on protest centers.

At the same time, "armed criminal gangs" killed one officer and four policemen, state news agency SANA said.
