Pakistan, included on a so-called grey list compiled by the FATF, has been under increasing pressure to stop the financing of militant groups Mumbai attacks, which killed more than 160 people LAHORE: Pakistani authorities on Thursday arrested four aides of extremist leader Hafiz Saeed, the suspected mastermind of a four-day militant attack on the Indian city of Mumbai in 2008, on terrorism financing charges, counter-terrorism police said. Saeed, arrested on the same charges, has been on judicial remand since July, a move welcomed by U.S. President Donald Trump who wants Pakistan to do more to crack down on militancy. But Saeed"s arrest came just ahead of a visit to Washington by Prime Minister Imran Khan and was seen by rival India as a ploy to smooth the way before a meeting with Trump. Thursday"s arrests come ahead of a meeting next week of the Financial Action Task Force, a global watchdog, which will review progress made by Pakistan on controlling terror financing and money laundering. Pakistan, included on a so-called grey list compiled by the FATF, has been under increasing pressure to stop the financing of militant groups. The four aides will appear before a trial court on Friday, police said in a statement. Saeed, designated a terrorist by the United States and the United Nations, is the founder of Lashkar-e-Taiba, or Army of the Pure, the militant group blamed by the United States and India for the Mumbai attacks, which killed more than 160 people. The United States has offered a $10 million reward for information leading to Saeed"s conviction. He has denied any involvement and said his network, which includes 300 seminaries and schools, hospitals, a publishing house and ambulance services, has no ties to militant groups.
