Pakistan summoned Britain's envoy in Islamabad on Monday over comments by British Prime Minister David Cameron suggesting it was not doing enough to fight terrorism, Reuters quoted officials. Adam Thomson, the British High Commissioner to Pakistan, was summoned to the foreign ministry to clarify remarks Cameron made during a visit to India last week, a Pakistani official said. A British Foreign Office spokesman confirmed that Thomson was meeting Foreign Minister Shah Mehmood Qureshi at the request of Pakistan's foreign ministry but gave no further details.
