KARACHI, Pakistan (AP) — Pakistani police used tear gas and batons yesterday to disperse anti-US protesters in the southern port city of Karachi, while in the federal capital Islamabad the foreign office issued a terse announcement that it cancelL ed this week’s visit by a senior US delegation.

Alice Wells, Washington’s special representative for Pakistan and Afghanistan, had been scheduled to meet Pakistani officials this week in Islamabad. No reason was given for the cancellation but it was apparently linked to the uncompromising demand made last week by President Donald Trump that Pakistan shut down safe havens for Afghan Taliban. Pakistan says it has no safe havens for the Taliban.

“At the request of the Government of Pakistan, the visit of the US delegation has been postponed until a mutually convenient time,” the Pakistan foreign office statement said.

Meanwhile in Karachi, police officer Irfan Baloch said police took action when a group of Shiite students tried to march toward the US consulate; an officer was injured in the process.

Trump, in a speech announcing a new strategy for Afghanistan and South Asia said Washington wanted an immediate end to militant sanctuaries, particularly to members of the Haqqani network blamed for some of the worst attacks in Afghanistan.

In Islamabad, a group held a peaceful Defense of Pakistan rally condemning US policy yesterday.
