U.S. Secretary of State John Kerry warned Thursday that the conflict raging in Syria could cleave it into rival enclaves, as he prepares for weekend talks on the crisis in Turkey.

The aim of the next Friends of Syria talks in Istanbul on Saturday is "to get everybody on the same page with respect to what post-Assad" Syria will look like, Kerry told U.S. senators, highlighting the need to ensure that "Qataris, Saudis, Emirates, Turks, Europeans" all have the same goals in mind.

Kuwait has donated $15 million to the United Nations to help war-torn Syria's 500,000 Palestinian refugees, the United Nations said on Thursday.

The U.N. agency for Palestinian refugees, UNRWA, says half of the Palestinian refugees in Syria have been internally displaced by the conflict and that 45,000 have fled to neighboring Lebanon and Jordan.

Lebanon's envoy to the United Nations Nawwaf Salam requested on Thursday sharing the burden of Syria's refugees with Arab states, confirming that no Syrians have been deported back to their country.

"The number of Syrians in Lebanon could reach 1.2 million by the end of 2013 and many Palestinian families are expected to enter Lebanon,” Salam warned at a U.N. Security Council session that discussed the situation of Syria's children in the midst of the country's conflict.

Syrian troops captured a strategic village in central Homs province on Wednesday with the help of Hizbullah, putting pressure on rebel forces in the area, the Syrian Observatory for Human Rights watchdog said.

The army seized Abel, on the main route between the city of Homs and Qusayr, a rebel stronghold near the border with Lebanon, the Observatory said.

Jordan is being dragged into Syria's conflict as more and more U.S. troops head to Amman, analysts say, amid a warning by Syrian President Bashar Assad the kingdom could be engulfed by his country's war.

"The escalation has become public. At the beginning of the crisis Jordan was trying to deal with it calmly, but now things are heading towards confrontation," Labib Kamhawi, a writer and political analyst told Agence France Presse.

With the conflict ravaging his country in its third year, Syrian President Bashar Assad is maintaining a hardline stance, insisting he will triumph over rebel forces and all but ruling out dialogue.

In an interview broadcast on Wednesday, the embattled leader struck a combative tone, again dubbing the opposition forces fighting his regime as "terrorists" and saying there was "no option but victory."

Kuwait has come through with the $300 million it pledged towards aid for stricken Syrians at a January donor's conference, the emirate and the United Nations said Thursday, urging other nations to follow its lead.

"We are ... matching our words with our deeds," Kuwait ambassador Dharar Abdul-Razzak Razzooqi told reporters in Geneva, detailing how the cash had been split between nine U.N. agencies and the International Committee of the Red Cross.

Jordan said on Thursday it was against military intervention in neighboring Syria, as more U.S. troops head to Amman and amid a warning by President Bashar Assad that the crisis could engulf the kingdom.

"Our position on the situation in Syria has not changed," Information Minister Mohammad Momani told Agence France Presse. "We are still against any military intervention in Syria. We urge a political solution to end the bloodshed in Syria."

Israel's Benjamin Netanyahu has urged caution over international calls to arm Syrian rebels and reserved the right for the Jewish state to block the supply of weapons that could be turned against it.

Speaking to the BBC, the Israeli prime minister said if advanced arms fell into the hands of Islamist militants it could redefine regional security threats.

U.S. Defense Secretary Chuck Hagel declined Wednesday to discuss Syria's possible use of chemical weapons against rebels, raising doubts over whether Washington still views such action as a "red line."

President Barack Obama has repeatedly warned Damascus against resorting to chemical weapons, hinting that the use of such arms or the prospect of militant groups gaining control of them could prompt a U.S. military intervention.
