ISLAMABAD, May 16 (IslamOnline.net) - Pakistani law enforcement officers arrested Friday, May 16, a group of alleged terrorists from southern city of Hyderabad on charges of links with Al-Qaeda, including its top computer expert who allegedly worked closely with Osama bin Laden.

Safwan Ul Hasham was taken into custody from a Karachi-bound passenger bus near Hyderabad, a police spokesman told reporters.

Later police raided an apartment in a nearby locality and recovered compact disks and other computer-related material and arrested ten companions of Hasham. Some of the arrested were said to be Arabs.

Police sources said the confiscated material had undated video images of bin Laden.

“It appeared that Hasham was preparing a local language version of Osama’s lectures to distribute among the followers” a senior police officer told IslamOnline.net over the phone from Hyderabad.

Hasham, a Saudi, was known to be Al-Qaeda’s top computer expert and was also in charge of intra organizational communications.

The arrests have been made a day after the chain of bombing at Karachi’s 21 foreign-owned gas stations.

No one was injured in these small explosions but they caused widespread alarm about the security situation in the volatile city.

"Their aim was not to kill, but perhaps to put across a message that foreign interests are under threat," said Aftab Sheikh, head of Karachi's provincial interior ministry.

Law enforcers were also looking into links between these blasts and Riyadh explosion which killed about 34 on Monday.

Sources said a joint Pakistan-U.S. interrogation team was interrogating Al-Qaeda suspects about possible links to Riyadh bombing.

Pakistan has arrested around 500 suspected terrorists since the start of the U.S.-led anti-terror campaign following September 11 attacks on the U.S.

President General Pervez Musharraf will meet with U.S. President George W Bush in Washington next month in the wake of reports that Al-Qaeda and other terrorist networks were re-grouping in Afghanistan and Pakistan and regaining ability to launch terror attacks.

Reports suggest that these groups are now visible in the border areas between the two countries.

According to an official announcement, Musharraf will be traveling to U.S. on June 24 on a seven-day official visit.

The Pakistan leader said earlier this month that bin Laden may be hiding in the areas along Pak-Afghan borders.

Islamabad has earlier been marinating that bin Laden was “most probably dead”.

Media reports quoted some senior intelligence officials as saying that new reports and evidence shown to Musharraf convinced him that not only bin Laden was alive, he was active in areas along Pakistan Afghanistan borders.

Some western media organizations have even suggested that Riyadh bombers had links in Pakistan.

This revival of terrorists in the region was the main subject of meetings of Pakistan’s top intelligence officer in the U.S. earlier this month.

Lt Gen Ehsan, chief of Pakistan secret service (ISI) met senior U.S. officials in his over two weeks stay in the US early this month.

“Afghanistan and anti-terror campaign in Pakistan top the proposed agenda of talks in the U.S.” a senior government office said.

He added that the latest interaction between the U.S. and Pakistan suggest that with the end to the Iraq war, U.S. policy makers were again shifting there attention to the anti-terror campaign in this region.

U.S. Deputy Secretary of State Richard Armitage and Assistant Secretary Christina Rocca last week concluded an assessment tour to Pakistan and Afghanistan.
