Yemen's dominant Houthi group accepted a five-day humanitarian cease-fire proposed by its adversary, Saudi Arabia, on Sunday but said it would respond to any violations of the pause.
Neighboring Saudi Arabia had said on Friday that the cease-fire could begin on Tuesday if the Iranian-allied militia agreed to the pause, which would let in badly needed food and medical supplies.
Backed by the United States, a Saudi-led coalition has been conducting airstrikes against the Houthis and army units loyal to ex-President Ali Abdullah Saleh since March 26 with the aim of restoring the government of President Abed Rabbo Mansour Hadi.
