AMMAN, Jordan — Saudi Arabia has agreed to an American request to provide a base to train moderate Syrian opposition fighters, American officials said on Wednesday.

“We now have the commitment from the Kingdom of Saudi Arabia to be a full partner in this effort — the train-and-equip program — to host that program,” said a senior Obama administration official, who added that discussions were underway to determine the specific site and other details.

The Saudi willingness to host a training program comes as Secretary of State John Kerry is preparing to fly to Jidda, Saudi Arabia, on Thursday morning for a high-level strategy session on how to counter the Islamic State in Iraq and Syria.

The meeting that is being hosted by the Saudis will also include senior officials from Arab states in the Persian Gulf region, as well as Egypt, Jordan, Lebanon, Turkey and Iraq.
