The prime minister of Pakistan, Shaukat Aziz, has called for European help in repatriating three million Afghan refugees in his country.
Mr. Aziz says refugee camps along the border with Afghanistan provide safe havens for terrorists.
The prime minister also promised to strengthen efforts to restrict cross-border attacks into Afghanistan. The Pakistan government has proposed a controversial plan to fence and mine parts of the mountainous border.
Mr. Aziz is in Belgium, holding talks with European Union and NATO leaders. After Tuesday's meeting, NATO Secretary General Jaap de Hoop Scheffer called for an end to criticism of Pakistan's efforts to contain militants. Scheffer said it does not make sense to have a public "blame game."
The Afghan government and the United States have both accused Pakistan of failing to clamp down on Taleban insurgents based in Pakistan who launch attacks into Afghanistan.
