Israel's attack in Qatar threatens to upend both negotiations over a ceasefire in Gaza and Israel's efforts to reach out to Gulf Arab states.

The leader of the UAE, Sheikh Mohammed bin Zayed Al Nahyan, who is also the ruler of Abu Dhabi, traveled Wednesday to Qatar in a visit that likely underscores the growing unease the Emirates feels with Israel.

In recent days, the UAE warned Israel that any effort to annex the West Bank, part of land the Palestinians want for their future state, would be a “red line” that would threaten the Abraham Accords.

Qatar’s ruler, Sheikh Tamim bin Hamad Al Thani, welcomed Sheikh Mohammed.

The two leaders had been on opposite sides of a political dispute for years during the first Trump administration that saw the UAE and three other nations boycott Doha.
