Havana, July 14 (RHC)-- Members of the 28th U.S.-Cuba Friendship Caravan, which make up Pastors for Peace, paid tribute Friday in Havana to the late Reverend Lucius Walker, founder of that inter-religious organization.

Gail Walker, executive director of Pastors for Peace, said that activists will demand that the administration of President Donald Trump keep the advances made by his predecessor, Barack Obama, and authorize U.S. citizens to travel freely to Cuba.

The caravan, which brought a donation of medicine, will travel through several Cuban provinces and visit churches and historical and social sites of interest.

About 30 U.S. citizens, along with Mexicans and Europeans, arrived in Havana on Thursday to support the demands for an end to the economic, financial and commercial blockade imposed by Washington on the Caribbean country more than 50 years ago.
