Key partners in the US-led coalition taking on Islamic State militants

The US-led coalition fighting Islamic State is growing, with dozens of countries among its ranks. The coalition is contributing a wide range of efforts, from carrying out air strikes to providing military assistance and humanitarian aid. Here are some of the coalition's key partners.

The US, which is leading the coalition, has launched dozens of air strikes on Islamic State targets. It has also sent military advisers, supplies and humanitarian aid to help Iraqi troops and Kurdish forces beat back the insurgents.

Saudi Arabia, the United Arab Emirates and Bahrain have participated in air strikes in Syria. A fourth country, Qatar, has played what the Pentagon called a supporting role. The Emirates and Qatar also host air bases that are being used for the US-led coalition's aerial campaign. Saudi Arabia has agreed to host training facilities for Syrian rebels on its territory.

Jordan has launched air strikes against Islamic State positions. The kingdom didn't give any specifics about its operations, but said the air strikes aimed to insure the country's security.

Egypt hasn't announced any specific participation in air strikes, but President Abdel-Fattah el-Sisi said Egypt was "completely committed to giving support" and would do "whatever is required" to aid the coalition.

Israel was offering intelligence estimates and concrete intelligence to the US on Islamic State as part of their ongoing intelligence sharing, an Israeli defence official said. But, he added, Israel wasn't asked to contribute anything beyond that.
