Sana'a: In a breach of ceasefire, a group of Al Houthi rebels attacked a checkpoint in Al Jawf province, killing a senior military officer, security sources said on Tuesday.
Five gunmen killed Colonel Ali Darban, 51, while on duty.
The incident breaks a ceasefire that was reached between the government and rebels only 4 days ago.
Meanwhile, displaced people have started to return to their villages in Sa'ada as the 6-year-old war forced about 250,000 to leave their houses.
