Pakistan's capital was locked down on Saturday, swarmed by security forces with mobile internet cut as supporters of jailed ex-prime minister Imran Khan attempted to seize the streets in protest.

The highlights this week: Pakistan’s opposition sounds off against proposed amendments to the constitution, the U.S. State Department’s top Afghanistan official moves on without a replacement, and police crack down hard on protests in Bangladesh.

Authorities in Pakistan sealed off the capital, Islamabad, and blocked cellphone services on Friday to prevent an anti-government rally by supporters of jailed former Prime Minister Imran Khan, officials said.
