GENEVA, Switzerland: A new United Nations human rights report on Yemen says Al-Qaida's local branch has become "operational" in the southwestern city of Taiz.

The city has faced "unrelenting" shelling in 2 1/2 years of escalated fighting in the impoverished country.

The report commissioned by the U.N. Human Rights Council, which re-convenes next week, also takes stock of the disastrous human rights situation in Yemen over much of the last three years.

Al-Qaida, the Saudi Arabia-backed internationally recognized government, and Shiite rebels known as Houthis are fighting in a country with devastated public services - home to what the U.N. calls the world's biggest humanitarian crisis.

The report Tuesday points to continuing human rights violations, security vacuums, recruitment of child soldiers and punishing airstrikes by a Saudi Arabia-led, U.S.-backed coalition.
