In brief: Suspected drug leaders arrested

TIJUANA, Mexico – Mexican federal police arrested two suspected gang leaders Monday, delivering another big blow to a brutal drug cartel that terrorized the border city of Tijuana for several years.

The capture of Raydel Lopez Uriarte and Manuel Garcia Simental apparently wipes out the existing leadership of the cartel headed by Teodoro Garcia Simental, who was captured last month. Teodoro and Manuel Garcia are brothers.

Lopez, known as “El Muletas,” and Garcia, known as “El Chiquilin,” were arrested Monday in La Paz, a city on the Baja California peninsula, a spokeswoman for the U.S. Drug Enforcement Administration said.

Dubai tower deck closed to visitors

DUBAI, United Arab Emirates – The world’s tallest skyscraper has unexpectedly closed to the public a month after its lavish opening, disappointing tourists headed for the observation deck.

Electrical problems are at least partly to blame for the closure of the $1.5 billion Burj Khalifa’s viewing platform – the only part of the half-mile high tower open yet.

Colonel charged with two murders

TORONTO – The commander of Canada’s largest Air Force base has been charged with first-degree murder in the deaths of two women.

Ontario Provincial Police Det. Insp. Chris Nicholas said Monday that Col. Russell Williams, 46, was also charged in the sexual assaults of two other women. Williams was arrested Sunday in Ottawa.

Williams, a 23-year military veteran, was appointed as the base commander of Canadian Forces Base Trenton in Trenton, Ontario, last July.

Williams is charged with the first-degree murder of Jessica Lloyd, 27, of a Belleville, Ontario, resident whose body was found earlier Monday, and Marie Comeau, a 38-year-old corporal found dead in her Brighton, Ontario, home in November.
