WASHINGTON, May 30 A Pakistani citizen, Mir Yaqub Bizenjo, has appeared on a White House list of the world's four leading drug barons.

On Friday evening, the White House issued an order signed by President Barack Obama, seeking sanctions against four alleged drug smugglers from Pakistan, Colombia, Venezuela and Afghanistan under a federal law known as the Kingpin Act.

The US Treasury's Office of Foreign Assets Control issued a notice saying that Mr Bizenjo had two given names, Mohammad Hyat or Mir Yaqub. But he was better known by his alias, Imam Bheel.

He operates from Jiwani, Turbat and Gwadar while he has two dates of birth, one showing that he was born in 1946 while the other indicating that he was born in 1956. He uses both in his travel documents.

The US Treasury identifies him as a Pakistani national. Related data identify him as a drug baron of Makran, who has been a traditional ally of the BNP. In 2002, Mr Bizenjo also vowed to work for the success of General Musharraf through front-page ads in newspapers.

Also on the list is Haji Juma Khan of Afghanistan, Daniel Rendon Herrera of Colombia and Walid Makled Garcia of Venezuela.
