Truce ends as rebels threaten drone attacks

Hopes for a fresh truce in Yemen were dealt a blow over the weekend as Houthi rebels boycotted UN-brokered peace talks and threatened further drone strikes against progovernment forces. The threat came days after a Houthi drone attack on a government military parade in the southern province of Lahaj killed several people. A senior intelligence official injured in that attack died of his wounds yesterday. Yahya Sarea, a Houthi spokesman, called the strike a ‘‘legitimate operation against aggression’’.
