Al-Qaida confirms its No. 2 killed in US strike

BEIRUT (AP) -- The Latest developments on the ground in Syria and at the Geneva peace talks. (all times local):

7:40 p.m.

Al-Qaida has confirmed that its deputy leader, known as Abu al-Khayr al-Masri, was killed in a U.S. airstrike in Syria.

The group praised al-Masri as a hero and "wise leader" with a "long career of contributions" to holy war, or jihad, in a statement on Thursday.

It says he was killed in a "Crusader strike" in Syria, calling it "another in the crimes of America and its Crusader alliance."

The SITE Intelligence Group, which monitors extremist organizations, said al-Masri - the nom de guerre of Egyptian militant Abdullah Mohammed Abdulrahman - may have been killed in a strike on Sunday on a vehicle in Syria's northwestern Idlib province.

Al-Masri was general deputy to Ayman al-Zawahiri, who became the top leader of al-Qaida when Osama bin Laden was killed by U.S. forces in Pakistan in 2011.

Syria's military has announces that it has fully recaptured the historic town of Palmyra from the Islamic State group for the second time in a year.

The army statement released on Thursday evening says that government forces are now in control of the town, following a series of military operations and with the help of Russian air cover and in cooperation with "allied and friendly troops" - shorthand for Lebanese Hezbollah fighters.

IS defenses of the town had begun to erode on Sunday, with the government troops reaching Palmyra's outskirts on Tuesday.

This is the government's second campaign to retake the desert town. It seized Palmyra from Islamic State militants last March only to lose it again 10 months later. Before the civil war gripped Syria in 2011, Palmyra was a top tourist attraction, drawing tens of thousands of visitors each year.

The Kremlin's spokesman says President Vladimir Putin has been informed by Russia's defense minister that Syrian government forces have taken control of Palmyra, with support from Russian warplanes.

Dmitry Peskov says Putin was given the report on Thursday by Defense Minister Sergei Shoigu, according to Russian news agencies. The reports did not give details or elaborate on the extent of Russian air support.

Syrian state media said the government forces battling the Islamic State group re-entered Palmyra earlier in the day, aiming to retake the historic town that they had lost to the militants in December.

U.S.-backed Syrian Kurdish troops say Russia has brokered an agreement between them and Turkish-backed opposition fighters. The deal seeks to avoid clashes between the two mutually hostile rivals, both fighting the Islamic State group in northern Syria.

The Manbij Military Council, part of the Kurdish-led Syrian Democratic Forces, says that under the deal, they will withdraw from a front line as rival Turkish-backed forces near the Euphrates River.

This will allow Syrian government forces to create a buffer between them.

However, Turkish Foreign Minister Mevlut Cavusoglu told reporters in Ankara there was no such agreement between Russia and the Syrian Kurds.

Kurdish-led forces captured the northern town of Manbij from IS last August, prompting Turkey to deploy troops into northern Syria.

Turkey considers the Kurdish forces a terrorist organization, linked to its home-grown Kurdish insurgency. Turkish troops are stationed in the Syrian town of al-Bab, 40 kilometers (25 miles) southwest of Manbij.

Syrian state media say that military forces have entered Palmyra in the quest to again take the town from the Islamic State group.

Palmyra, home to some of the world's most prized Roman ruins, was seized again by IS in December.

Syria's state news agency SANA says that government troops entered the town's archaeological site on Thursday. It said IS militants were fleeing from the area.

IS defenses began crumbling on Sunday, with the government reaching the town's outskirts on Tuesday.

Activist-run Palmyra News Network says the advancing forces have pounded the town with artillery and airstrikes.

This is the government's second campaign to retake Palmyra. It seized the town from Islamic State militants last March only to lose it again 10 months later.

Turkey's foreign minister says with the completion of an operation to retake the Islamic State-held town of al-Bab, Turkish troops will head to Syrian town of Manbij next, to oust it of U.S.-backed Syrian Kurdish forces that Ankara views as terrorists and a threat to Turkey.

Foreign Minister Mevlut Cavusoglu on Thursday said Turkey would not shy away from attacking the Kurdish group that dominates the Syria Democratic Forces and which captured Manbij last year after weeks of deadly fighting with the Islamic State group. He renewed calls for the new U.S. administration not to support the Kurdish forces.

Cavusoglu added that an operation to take Manbij had not started yet, but acknowledged that skirmishes between Turkish-backed forces and the Kurdish fighters may have occurred.

The United Nations envoy to Syria is working round the clock in a bid to secure a modest victory in the fourth round of talks held in Geneva.

Staffan de Mistura is due for another round of meetings Thursday marking a week of bilateral talks with the government delegation and opposition groups.

A top Syrian opposition negotiator told journalists overnight Wednesday the "envoy is really keen to start a political process on the basis of a clear agenda."

Nasr al-Hariri said the talks would likely culminate in a closing ceremony Friday and the parties may be back in Geneva for further discussions in a few weeks.

Setting the agenda and strategy to guide discussions has proven difficult as the main conflicting parties dig in their heels over form and semantics.
