Iran urges Pakistan action after attack

TEHRAN (Reuters) - Iran has received information that "some security agents" in Pakistan were cooperating with elements behind Sunday's attack on the Revolutionary Guards, President Mahmoud Ahmadinejad was quoted as saying.

Ahmadinejad called on Pakistan not to waste time in cooperating with Iran in apprehending the perpetrators, the semi-official Fars News Agency reported.

Iran has in the past accused Pakistan of hosting members of the Sunni insurgent group Jundollah, Iranian state television said. Iranian media say Jundollah claimed responsibility for Sunday's bombing, which killed more than 30 people.

Some analysts believe Jundollah has evolved through shifting alliances with various parties, including the Taliban and Pakistan's ISI intelligence service, who saw the group as a tool against Iran.

"We were informed that some security agents in Pakistan are cooperating with the main elements of this terrorist incident ... We regard it as our right to demand these criminals from them," Ahmadinejad said, without giving details.

"We ask the Pakistani government not to delay any longer in the apprehension of the main elements in this terrorist attack," he said.

State television said Iran's Foreign Ministry summoned a senior Pakistani diplomat in Tehran, saying there was evidence "the perpetrators of this attack came to Iran from Pakistan."

"The Pakistani official assured Tehran that his country would take all measures to secure its border with Iran," English-language Press TV added.
