Pakistani President Asif Ali Zardari will visit Afghanistan on Tuesday for talks with his Afghan counterpart Hamid Karzai, the Foreign Ministry said in a statement, Xinhua reported.
"During the visit President Asif Ali Zardari and President Hamid Karzai will discuss issues of bilateral importance as well as the regional and international situation," the statement said.
Zardari will offer condolences to Karzai over the demise of his brother, Ahmad Wali Karzai, who was killed by his guard last week. Taliban had claimed responsibility for the attack.
Official sources said that Zardari will raise the issue of alleged incursion of militants from Afghan side of the border into Pakistan, who Pakistan army says attacked border checkpoints and villages, killing nearly 50 security personnel.
Afghan authorities said that Pakistani forces had fired rockets and artillery shells into Afghan provinces of Kunar and Nangarhar, causing civilian casualties.
Senior Afghan, Pakistani and U.S. military officials met in the northwestern Pakistani city of Peshawar this month and discussed border tension and agreed to hold more talks.
Pakistan army spokesman Major General Athar Abbas said that Pakistani Taliban had used the Afghan soil as launching pad for attacks on Pakistan. At least two top leaders of Pakistani Taliban, namely Maulvi Faqir Muhammad and Maulana Fazalullah, are now operating from Afghanistan.
Afghan officials rejected Pakistan's claim and Governor of Kunar province Fazaullah Waeedi asked Islamabad to share intelligence about Pakistani Taliban.
