The Ministry of Health of the Kingdom of Saudi Arabia today advised pilgrims, who started pour in the holy places to attend pilgrimage in Makkah in the coming few weeks, to avoid direct sun rays, high temperatures and crowds while performing their rituals in the holy city of Makkah and other holy places. Pilgrims are advised also to take as much fluids as possible, resort to rest and use light-colored umbrellas to avoid sun strokes, the ministry tweeted. This year's Hajj falls in a hot summer.
