Peruvian President Pedro Castillo imposed a curfew in the capital, Lima, in an attempt to curb protests against rising fuel and fertilizer prices that have spread across the country, Reuters reported.

The cabinet agreed to announce a ban on the movement of citizens from 2:00 to 11:59 Tuesday, April 5, to protect the fundamental rights of all people, Castillo said.

On Monday, a wave of protests against rising fuel and fertilizer prices sparked by the Ukrainian crisis continued into its second week as the government tried to lower prices.

The protests are becoming increasingly violent, with at least four people killed, the government said.

The riots erupted last week when farmers and truckers blocked some of the main highways leading to Lima, causing a sudden spike in food prices.

The government responded over the weekend with a proposal to eliminate most fuel taxes in an attempt to lower prices, as well as raise the minimum wage by about 10% to 1,205 soles ($332) a month.

Peru has also declared a state of emergency for its agricultural sector due to rising fertilizer prices caused by Western sanctions on Russia, a major exporter of potassium, ammonia, urea and other soil nutrients.

Like many countries, Peru struggled with high inflation even before the war. In March, inflation reached a 26-year high, mainly due to rising fuel and food prices.
