Here’s a summary of today’s key events:

Syria

• A video has been published purporting to show six of the 21 Filipino UN peacekeepers captured by a group calling itself the Martyrs of Yarmouk Brigades on Wednesday. In the video one uniformed man identifying himself as a captain in the Filipino battalion says the group are safe but implies they have been split up. He says civilians took them for their own safety and have given them food and drink. That doesn't fit with previous videos purporting to show armed men surrounding UN peacekeepers in their vehicles.

• Talks are under way between a UN commander and the leader of the Yarmouk Brigades to free the peacekeepers. In a video that purported to show the kidnappers and some of the kidnapped peacekeepers, a member of the Yarmouk Brigades said the group would hold the Filipinos until Syrian government forces withdrew from the village of Jamlah, just east of the Golan Heights. The group said if this pull-out did not happen within 24 hours “we will deal with the UN force members as prisoners”. But there were reports of fighting around the Jamlah area, prompting the Yarmouk Brigades to post a statement warning that the Syrian army would be blamed if the peacekeepers were harmed. The UN demanded the immediate and unconditional release of the peacekeepers.

• A spokeswoman for the Syrian National Coalition, the main umbrella grouping of the Syrian opposition – which yesterday heard that the UK would be providing it with an extra £13.2m ($20m) of non-lethal aid – said it was in contact with Free Syrian Army troops in order to negotiate the release of the UN peacekeepers. “We confirm that it's not a kidnapping operation, it's just a preventive security measure,” she said. Asked if the incident fuelled criticism of western countries such as Britain giving aid to the Syrian rebels, Najib Ghadbian, the Syrian National Coalition’s ambassador to the US and the UN, denied this, pointing out that "the Free Syrian Army is not all unified" and saying that "it’s not unlikely to find a group here and there who are not necessarily part of that structure". But he said that the SNC was “doing everything we can to bring this to a positive ending”.

• The Philippines said it was working with the UN, US, UK, France and Germany to secure the release of the peacekeepers, calling their kidnapping and detention “gross violations of international law”. Foreign affairs department spokesman Raul Hernandez said that the peacekeepers were unharmed and were being treated as "visitors and guests". Israel said the UN could handle the matter and it would not interfere. The Golan Heights is occupied by Israel and the peacekeepers were there to monitor the ceasefire between Israel and Syria since the end of the Yom Kippur war of 1973. The 21 peacekeepers – three officers and the rest enlisted personnel – were in a four-vehicle convoy when they were intercepted by Syrian rebels around noon on Wednesday, Philippine military spokesman Colonel Arnulfo Marcelo Burgos said.

• Human Rights Watch is investigating whether the Martyrs of Yarmouk Brigades were also involved in the executions of captured regime soldiers in another incident around Jamlah several days ago.

• The Syrian government said it had uncovered an Israeli spy camera monitoring a “sensitive site” on its Mediterranean coast.

• The Local Co-ordination Committees, a Syrian opposition group, reported that 25 people had been killed in fighting across the country today, including nine in Idlib, in the north-west. Videos purported to show warplanes shelling areas of Idlib, Homs and Deir Ezzor. These reports and videos cannot be verified because most media are banned from Syria.

• Medecins Sans Frontieres said there had been a “complete collapse” of the healthcare system in Syria, in a new report. “Medical aid is being targeted, hospitals destroyed and medical personnel captured,” said Dr Marie-Pierre Allié, president of MSF.

• The Syrian National Coalition, the umbrella organisation for the Syrian opposition, is to meet in Istanbul on Tuesday to elect a provisional prime minister, coalition members told Reuters.

Libya

Police and army units have deployed in strength across the Libyan capital after an attack by rogue militias forced the country's legislature to consider suspending its activities.

Tunisia

Tunisia's ruling Islamist party Ennahda has failed to bring more secular parties into a coalition government due to be formed by Friday to oversee elections in a transition process upset by the assassination of a leftist politician.
