A Roman Catholic priest has trekked hundreds of miles from his parish. Tribesmen marched barefoot from the southern Amazon jungle carrying spears. They will be joined by disabled activists from Barquisimeto who will push their wheelchairs through the streets.  Venezuela’s opposition hopes these protesters will be among hundreds of thousands who will join a rally in Caracas on Thursday to demand a vote to recall the president, defying government warnings of a severe crackdown if demonstrators “step over the line”.  Opposition leaders called on marchers to “take Caracas” and demand the electoral council set a date for a recall vote to oust the unpopular Nicolás Maduro, after the electoral authorities this month cast doubt over the vote. The government in turn urged loyalists to attend rival rallies to prevent what it described as a US-sponsored coup amid signs it is clamping down on dissidents.
