Sri Lanka Cricket on Tuesday turned down an invitation by Pakistan to return to the troubled nation, saying security was still a problem two years after its players were attacked there. "We are not going to send our team to Pakistan," Sri Lanka Cricket chairman D.S. de Silva told a foreign news agency. "I have asked the secretary to inform the Pakistan Cricket Board today (Tuesday) of the decision. "We have instead requested Pakistan to host the matches in Colombo or at a neutral venue like Dubai or Abu Dhabi," he said. The Pakistan Cricket Board announced at the weekend that they had invited Sri Lanka to play three Tests, five one-day internationals and one Twenty20 game in a series proposed for October.
