Russia insisted Tuesday it would deliver anti-aircraft missiles to Syria despite international criticism, as fears of spillover from the conflict grew after three Lebanese soldiers were killed in a border-area attack. Israel warned Russia it would "know what to do" if the delivery went ahead, and Syria's top rebel commander gave Hezbollah, the powerful Lebanese Shia movement, a 24-hour ultimatum to stop fighting alongside regime forces.
The developments stoked tensions after the European Union decided to lift an embargo on weapons to Syria's rebels, in a move the opposition reacted to with caution. Syria's regime joined its ally Russia in condemning the EU decision as an "obstruction" to peace efforts, while accusing the bloc of supporting and encouraging "terrorists".
Moscow said it would go ahead with its plans to deliver the S-300 missiles to Syria, despite international concerns, saying the weapons were part of existing contracts. "We consider these supplies a stabilising factor," deputy foreign minister Sergei Ryabkov said, adding they could act as a deterrence against foreign intervention. Israel has strongly objected to the delivery, and its defence minister warned of a response.
"The deliveries have not taken place, and I hope they do not. But if, by misfortune, they arrive in Syria, we will know what to do," said Moshe Yaalon. Israel has reportedly carried out at least three strikes against Syria since the uprising against President Bashar al-Assad erupted in March 2011, apparently targeting weapons sites.
On the ground, the conflict has already spilled over into Lebanon, and in the latest incident three soldiers were killed in an attack near the Syrian border. The army said the attack came in the early hours near Arsal, a north-eastern Lebanese town in where most residents back Syria's uprising. And in the eastern Lebanese town of Hermel, a Hezbollah stronghold, security sources said six rockets apparently fired from Syria landed in the area throughout the day, wounding seven people.
Hezbollah is allied with the Syrian regime and fighting alongside the army against rebels, including in the central town of Qusayr, where it has lost dozens of men. Its role has raised fears Lebanon could be dragged into the Syrian war, and rebel chief Salim Idriss warned his fighters would respond within 24 hours if the group failed to halt its intervention.
"If the attacks of Hezbollah against Syrian territory do not stop within 24 hours, we will take all measures to hunt Hezbollah, even in hell," he told Al-Arabiya news channel. The tensions overshadowed an ongoing meeting in Istanbul of the National Coalition, Syria's main opposition group, which responded cautiously to the EU's decision to lift its arms embargo on the rebels.
"Definitely it is a positive step, but we are afraid it could be too little, too late," Coalition spokesman Louay Safi told AFP. The EU agreed Monday to lift the embargo, but no member state intends to send any weapons immediately for fear of endangering the prospects for a peace conference.
The move divided the 27-member bloc, with Britain and France in favour and Austria, the Czech Republic, Finland and Sweden reticent to pour more arms into a conflict that has already cost some 94,000 lives. But even with the lifting of the embargo, countries are expected to hold off on sending weapons to the rebels to allow efforts to convene the peace conference dubbed Geneva 2 that Russia and the United States are trying to organise as early as next month.
The opposition is still discussing whether to attend the conference, and Russia insisted Tuesday that Iran - a key Assad backer - must be invited, despite Western reservations. "The issue of Iran is key for us," Russian media quoted Foreign Minister Sergei Lavrov as saying.
