Sen. John McCain is worried Egypt may be heading toward prolonged violence after a contentious meeting with the Arab country's top general.

McCain said Gen. Abdel-Fattah el-Sissi is unhappy with some of the suggestions he and fellow Republican Sen. Lindsey Graham made this week during a visit to Cairo. One focused on releasing some Muslim Brotherhood leaders imprisoned after last month's coup.

McCain said he regrets that el-Sissi isn't ready to enter a dialogue with the Brotherhood and that the Brotherhood isn't ready to commit to nonviolence. The Arizona Republican said the standoff could end up violent if negotiations don't start.

He told The Associated Press by telephone Thursday the Senate's support of aid for Egypt may change if the military doesn't quickly restore democracy there.
