Pakistani supporters of Islamist leader Hafiz Saeed staged small protests on Tuesday and condemned the United States, after police detained the accused architect of an attack on the Indian city of Mumbai that killed 166 people in 2008, APA reports quoting Reuters.
Saeed, pointed to by critics as evidence of Pakistan's reluctance to crack down hard enough on militants, was held late on Monday at the headquarters of his charity before being placed under house arrest at his home in the eastern city of Lahore.
He denies involvement in the Mumbai attack.
The move follows a U.S. visa ban by President Donald Trump aimed at countries deemed linked to terrorism, and, while Pakistan was not named, a Pakistani official said worry over the new administration was a factor in the decision.
Pressure from key ally China may also have played a role, according to senior Pakistani officials, who say Beijing has for months been quietly lobbying Islamabad to crack down on Saeed and other Islamist leaders.
"Release Hafiz Saeed! ... Anyone who is a friend of the U.S. is a traitor!" chanted about 150 members of Saeed's Islamic charity Jamaat-ud-Dawa (JuD) in the southern city of Karachi.
About 500 protesters shouted similar slogans outside the provincial assembly in Lahore. Demonstrations also were held in Islamabad, according to the JuD, which the United States says is a front for the Lashkar-e-Taiba (LeT) militant group blamed for the Mumbai attack.
Saeed founded LeT in the 1990s but later distanced himself from it.
Arch-rival India was skeptical that Pakistan would bring Saeed to justice, pointing out that he had been detained before and released.
"Only a credible crack down on the mastermind of the Mumbai terrorist attack and terrorist organizations involved in cross border terrorism would be proof of Pakistan's sincerity," said a statement from India's Ministry of External Affairs.
