Sanaa, July 24 (TIWN) A total of 13 children were injured in an attack carried out by the Houthi militia against a residential neighbourhood in Yemen's southwestern province of Taiz, a security official said.

The attack coincided with the arrival of a high-ranking UN delegation to Taiz, the third largest city in Yemen, to push the warring sides in Yemen to extend the truce that expires on August 2.  During the past days, Yemen's Houthis carried out a series of attacks against various areas of the war-ravaged Arab country, as UN Special Envoy for Yemen Hans Grundberg stepped up his effort to extend the Yemeni truce.  Several rounds of negotiations between the government and the Houthis were conducted under the auspices of the UN but failed to achieve any progress toward ending Yemen's years-long military conflict.  The Houthi militia backed by Iran set new conditions to accept the UN proposal to extend the truce with the Saudi Arabia-led coalition for another six months.  As hopes for truce extension begin to fade, political observers said that the possible failure to break the years-long political stalemate on Yemen's issue will badly affect the Yemeni people aspiring for permanent peace.  The truce in Yemen, first enforced on April 2 and renewed for another two months on June 2, will expire on August 2.
