ISTANBUL, Turkey After a contentious debate over policy toward Syria, the European Union agreed Monday to let its embargo on arms shipments to Syrian rebels and the Syrian government expire at the end of the month, possibly the best news that the beleaguered forces battling to topple President Bashar Assad have had since their uprising began 26 months ago.
William Hague, the British foreign secretary, said there was "no immediate decision to send arms" to the rebels, in a tweet reported by the British Broadcasting Corporation.
Britain and France had been the main backers of an end to the embargo, which expires Thursday, while Austria, Sweden and the Czech Republic were among those objecting.
The news upstaged a dramatic show of support for the rebels by U.S. Sen. John McCain, who slipped into Syria earlier Monday from southern Turkey and met with Salim Idriss, the defected Syrian general who heads the opposition's Supreme Military Council, the group through which the United States and other nations have agreed to route all military and nonlethal assistance.
Still, it remained to be seen if those morale-boosting developments could overcome the deep disarray that engulfed a conference of leaders of Syria's political opposition, who completed a fifth day of meetings without agreement on a range of issues, including expanded membership and what to do about a proposed peace conference tentatively set for next month.
A decision by the Syrian opposition on whether to participate in the Geneva talks and under what conditions had been on the agenda of the coalition in its closed-door conference that began last Thursday, but that and the formation of a government-in-exile and even the election of new leaders seemed out of reach early today as delegates continued to wrangle over how to expand the coalition's membership.
Meanwhile, in Paris, Secretary of State John Kerry met his Russian counterpart, Sergey Lavrov, to go over plans for a peace conference on Syria next month in Geneva. Syria announced Sunday that it would send a delegation to the Geneva talks, but spoke of starting a "dialogue" with rebels rather than negotiating a transition to a post-Assad regime, as the U.S. has demanded.
Lavrov told reporters that organizing the conference was "a tall order" but said "the chances for success are there." According to Western diplomats, Russia insists that there be neither agenda nor preconditions for the talks and refuses even to ask the U.N. Security Council to enforce the outcome of the conference.
In his remarks, Kerry said the United States was committed to convening the conference, though there were many details that had yet to be agreed on, among them who should be invited to the conference besides Russia, the United States, the Syrian government and its opposition. Iran has asked that it be invited and Iraq announced on Sunday that it intended to participate. But Kerry indicated the guest list was still subject to U.S.-Russia negotiation.
McCain has publicly advocated arming the Syrian rebels, but he issued no statement after the visit. Idriss' headquarters are in the town of Bab al-Hawa, just across the border from Reyhanli, Turkey, where two car bombs killed more than 40 people three weeks ago. But it was unknown if that was the location of the meeting.
