ABUL, Afghanistan (AP) — The second-ranking U.S. general in Afghanistan said Monday it was too early to tell if the killing of al Qaeda leader Osama bin Laden in neighboring Pakistan will have an impact on the Afghan war effort.

U.S. Army Lt. Gen. David Rodriguez’s comments come as the United States tries to hang on to gains in Taliban strongholds, often at the cost of lives.

On Monday, a Pentagon official said four American service members were killed in a bomb attack in southern Afghanistan. The NATO international military command in Kabul provided no details on Monday’s attack, including the nationalities of the dead.

But in Washington a defense official said they were American and they were hit by an improvised explosive device. The official spoke on condition of anonymity because relatives of those killed were still being notified.

The latest deaths make a total of 16 NATO service members killed so far this month, and 167 so far this year.

Gen. Rodriguez, who is in charge of NATO‘s joint command, said that al Qaeda as a movement was not based on bin Laden’s leadership alone and that the military has been waiting to see how his May 2 death will affect the strength of the terror group and its influence in Afghanistan.

Gen. Rodriguez said bin Laden’s killing by U.S. Navy SEALs in the garrison city of Abbottabad had “no effects that we can see at this point. It’s too early to see that, but we are continuing to watch that over time.”

According to Gen. Rodriguez, al Qaeda has fewer than 100 operatives in Afghanistan, mostly providing support and resources to insurgents.

“The al Qaeda movement is not based on just one individual, and we will have to see what that impact is … and how much that will be on the strength of al Qaeda and associated movements. But that is yet to be seen,” Gen. Rodriguez said.

There has been hope that the killing of bin Laden will weaken the terror group’s connections with the Taliban, especially with leaders such as Mullah Mohammed Omar, who had personal ties to the dead al Qaeda leader. Pakistan also may feel pressured to help bring some Afghan Taliban leaders to the negotiating table. The Taliban’s leadership is thought to be hiding in Pakistan.

Afghan President Hamid Karzai, who often has called on Pakistan for help with the Taliban, has been pushing for reconciliation with the insurgents. The United States also has been promoting what it has called a diplomatic surge to help find a nonmilitary solution to the fighting.

Gen. Rodriguez predicted that violence would increase further this summer as the Taliban tries to retake territory it lost in southern Kandahar and southwestern Helmand provinces in the past year.

“We have said for several months that we will see a rise in violence this spring and summer. And as the Afghan government keeps gaining support from the people, the insurgents will continue to launch sensational attacks against soft targets,” Gen. Rodriguez said.

He added that Afghan and coalition forces would try to expand security around Kandahar and Helmand and link the two regions.

“These were the two centers of the Taliban movement, and the combined team holds them and intends to retain them. We know that the Taliban want them back, and we expect, and we are seeing him, continue to attack. But every day we hold them is one day more to build and harden the environment,” said Australian Maj. Gen. Michael Krause, the coalition’s deputy chief of staff for plans.

The Taliban recently launched a long-promised spring offensive and has carried out attacks in the southern and eastern parts of Afghanistan, near the border with Pakistan. The Taliban and other insurgent groups retain bases in safe havens across the border in Pakistan’s lawless tribal areas.

A Taliban mortar attack Monday in eastern Kunar province left three Afghan civilians dead and eight wounded. The intended target was a U.S. base, Combat Outpost Honaker Miracle, but the four mortars missed it, NATO said.

“Our Afghan national security and coalition forces are working diligently to counter the recently announced Taliban spring offensive,” said Afghan National Army Maj. Shereen Agha.

The coalition’s director of public affairs, U.S. Rear Adm. Vic Beck, said, “Each of these heinous attacks turns support away from their cause and strengthens the resolve of the people against them.”

NATO and the United States hope to start slowly relinquishing control for security to Afghan forces, with the eventual goal of handing over responsibility at the end of 2014. President Obama has said the United States, with about 100,000 troops on the ground, will begin a gradual drawdown in July — with the number to be determined by the situation at the time.
